Introduction
This introduction provides a basic understanding of mass spectra and explains how to use
Thermo Xcalibur™, the Thermo Scientific™ mass spectrometry data system for qualitative
analysis. Qualitative analysis focuses on solving two analysis problems:
• The identification of unknown compounds
• Trace analysis and the confirmation of target compounds

• Analysis Modes for the Mass Spectrometer
Understanding Spectra
There are many different types of mass spectrometry (MS) detectors but the basic principles
are the same in all cases: the MS ionizes the sample, separates the ions according to their
mass1, and moves the separated ions towards a detector where they are counted. The data
system compiles a spectrum showing the mass distribution of the ions produced from the
sample—a snapshot of ion intensities plotted against their mass-to-charge (m/z) ratios1.
Ionization initially produces molecular ions, but complex secondary processes can cause the
molecular ions to fragment. Together with molecular ions, these fragment ions make up the
mass spectrum. For individual chemical substances, a mass spectrum can be a characteristic
molecular fingerprint.
These topics describe some common features of mass spectra:
• Base Peak
• Neutral Losses
• Effect of Ionization Modes
• Adduct Formation
• Effect of Isotopes

Introduction
Understanding Spectra
Base Peak
In standard practice, the most abundant ion, called the base peak, is given an arbitrary
abundance or intensity of 100. The Xcalibur data system reports all other peaks as a
percentage of the size of the base peak. After this normalization, the data system can compare
spectra directly.
Figure 1 is an example of a simple library spectrum showing the fragmentation of acetone
C3H6O (molecular weight = 58 Da) in an electron ionization (EI) ion source. The most
abundant ions have been labeled with their mass-to-charge ratios. In this example, the
molecular ion (58 Da) is not the most abundant. The base peak is actually 43 Da because of
the acetyl ion.
Figure 1.
70 eV electron ionization (EI) mass spectrum of acetone
Neutral Losses
You can use fragmentation patterns like the pattern in Figure 1 to determine molecular
structure. For example, the neutral loss of 15 Da from the molecular ion of acetone indicates
the presence of a methyl group in the original molecule. A subsequent loss of 28 Da
corresponds to the loss of CO. Table 1 lists commonly observed neutral losses, measured by
the molecular weight of the compound. Assign such losses to help deduce the structure of an
unknown compound. A full structural analysis generally relies on the presence of a molecular
ion and the measurement of the molecular weight of the compound.

In some cases, fragmentation is extensive, leaving little or no trace of a molecular ion. With no
molecular ion, determining either the molecular weight or the structure is difficult.
Effect of Ionization Modes
The ionization mode affects the spectrum characteristics of a compound.These topics describe
the common ionization modes for LC/MS (liquid chromatograph/mass spectrometer) and
GC/MS (gas chromatograph/mass spectrometer) instruments:
• Ionization Modes for LC/MS Instruments
• Ionization Modes for GC/MS Instruments
Ionization Modes for LC/MS Instruments
LC/MS instruments use a variety of techniques, collectively called atmospheric pressure
ionization (API). Detectors of this type can be configured to detect positive or negative ions.
API techniques offer soft ionization, usually with little or no fragmentation. An API spectrum
typically contains only the protonated or deprotonated molecular ion. Compounds with
basic sites (such as amines) can form protonated molecules [M + H]+. These can be
analyzed in positive ion detection mode, giving an ion peak at the m/z value M+1 (where M
represents the molecular weight of the compound).
Compounds with acidic sites (sulphonic acids, for example) can form deprotonated
molecules [M–H]–. These can be analyzed in negative ion mode as ion peaks at the
m/z value M–1.

Introduction
Understanding Spectra
Ionization Modes for GC/MS Instruments
GC/MS instruments offer two techniques: electron ionization (EI) and chemical
ionization (CI).
EI is very commonly used because it is simple and reproducible. The fragmentation pattern is
effectively determined by the energy of the impacting electrons alone (electron energy,
measured in eV). Very different types of mass spectrometers that use EI can produce virtually
identical spectra as long as the electron energy is the same.
This reproducibility has led to an extensive library compilation for 70 eV EI spectra. With the
Xcalibur Library Browser, you can access the optional NIST/EPA/NIH Mass Spectral Library
with over 108000 reference EI spectra. You can use library data to select confirmatory ions for
your target compounds.
Chemical ionization (CI) offers a softer method of forming ions. In CI, a controlled flow of a
reagent gas, commonly ammonia, methane, or isobutane, is introduced into the area where
ionization occurs (the ion source). Energetic electrons that pass through the source ionize the
reagent gas, as in EI. These ions can then collide with neutral molecules, causing hydrogen
transfer. This process is repeated when the reagent gas ions collide with analyte molecules.
CI usually produces protonated molecules, generally at a mass one unit greater than the
molecular mass of the compound. Significantly less fragmentation occurs than in comparable
EI spectra. Depending on the choice of reagent gas, adduct ions can form. For example,
M+NH4 is a typical adduct ion when ammonia is used as the reagent gas.
Under certain conditions, CI produces negative molecular ions formed by electron capture.
The sensitivity of negative ion CI for certain classes of compounds (those containing double
bonds, sulfur, phosphorus, chlorine, or bromine) can be orders of magnitude greater than
positive CI or EI modes for those compounds.
For more information about the ionization modes available on your instrument, read the
hardware manual and the instrument manual on how to get started.

Understanding Spectra
Adduct Formation
If ionization takes place in the presence of contaminants or additives such as ammonium or
sodium ions, some compounds are susceptible to adduct formation. These spectra show other
ions in addition to, or instead of, the molecular ion (see Figure 2).
Figure 2.
Mass spectrum showing sodium and acetonitrile adducts

Take care when determining molecular weights to account for possible adduct ions.
Effect of Isotopes
In some cases, the effect of less abundant isotopes might cause you to use an average molecular
weight rather than one based on the most abundant isotopes. When the molecular structure
of the target compound contains large numbers of certain elements, the less abundant
isotopes become significant. This situation might result in a shift in the mass peaks from their
expected m/z values.

Introduction
Analysis Modes for the Mass Spectrometer
For example, the most abundant isotope of chlorine is Cl35. However, Cl37 occurs with a
natural abundance of 24.47 percent. If a compound contains four chlorine atoms, its
molecular ion is two mass units greater than that expected from a calculation based solely on
Cl35. Using chlorine’s average atomic weight (35.453), the molecular ion is correctly
identified. Also, you observe a distribution of molecular ions across eight mass units from
molecules containing between zero and four Cl37 atoms.
Analysis Modes for the Mass Spectrometer
A Thermo Scientific mass spectrometer has these analysis modes:
• Full Scan
• Selected Ion Monitoring (SIM)
• MS/MS
Full Scan
In full-scan operation, the MS detector scans repetitively over a wide mass range throughout
the analysis and sends the data to the data system computer.
With the Xcalibur data system, you can display the chromatograms (measured intensity versus
analysis time) for full-scan MS data in these ways (plot types):
• As a total ion current (TIC) chromatogram. A TIC chromatogram represents the
summed intensities of all the ions in the scanned mass range (mass spectrum) plotted
against the chromatographic retention time. Each peak in the TIC represents one or
more eluting compounds, which can be identified from the mass spectra recorded across
the peak.
• As a mass chromatogram for a range of masses within the scan range. Mass
chromatograms show the ion intensities of selected mass-to-charge ratios (m/z). The
Xcalibur data system extracts these mass spectra from each stored scan and plots them
against the analysis time. Use this technique to increase selectivity by displaying an
m/z value characteristic of the compound of interest but not present in other sample
components.
• As a base peak chromatogram. Base peak chromatograms show the ion intensities of the
most intense ions for each time point in the chromatogram.
The full-scan mode is suited to the identification of unknowns and can also be used for trace
analysis when sensitivity is not important.

Xcalibur Qualitative Analysis User Guide
Thermo Scientific
1 Introduction
Analysis Modes for the Mass Spectrometer
Selected Ion Monitoring (SIM)
In the SIM mode, the MS detector monitors a limited number of m/z values that are
characteristic of a targeted compound or compounds. During an analytical run, the mass
analyzer repeatedly switches between the selected m/z values and monitors each m/z value for a
programmed dwell time before averaging the measured ion intensities and moving on to the
next value.
SIM generates mass chromatograms only of the monitored m/z values, not complete mass
spectra as in the full-scan mode. Without a complete mass spectrum, you cannot perform a
library search to identify an unknown.
Selected ion monitoring (SIM) is ideally suited to trace analysis and offers reduced file sizes
compared to full-scan operation because SIM records only the information of interest.
MS/MS
Depending on your instrument, you might also be able to do additional stages of mass
analysis called MS/MS.
In an MS/MS experiment, an ion from the mass spectrum is selected for fragmentation while
all other masses are discarded. The selected ion, called a precursor (parent) ion, is then
collided with a neutral background gas. As a result of the collisions, the precursor ion is
broken into fragments called product ions. An ion trap mass spectrometer (a mass
spectrometer with an ion trap type of mass analyzer) can perform additional stages of MS
(called MSn), up to MS10.
The MS detector can monitor the product ions in either the full-scan mode or the SIM mode.
When you set up the MS detector to monitor a specific product ion of a specific precursor
(parent) ion, the scan type is called selective reaction monitoring (SRM).
You can create your own libraries of full-scan MS/MS data to use for matching.
You can display the chromatograms for full-scan MS/MS data in these plot types: TIC, mass
range, base peak, or neutral fragment. With the neutral fragment plot type, you must specify
the neutral fragment.

Using the Qual Browser Window
Thermo Xcalibur Qual Browser is a powerful and versatile utility for viewing chromatograms
and spectra from raw files or result files.
Note Raw files contain unprocessed data and result files contain data that has been
processed with a processing method. When you view raw files in Qual Browser, the data
system applies default integration settings to the chromatograms.
In the Qual Browser window, you can open a raw or result file, and display chromatograms,
spectra, and maps of the data. You can choose spectra from chromatograms, average scans,
subtract background data, create and save layouts, add text and graphics, apply filters, amplify
regions, and print the resulting graphic.
These procedures describe how to use some of the basic features of the Qual Browser window.

Identifying Inactive, Active, and Pinned Cells
Identifying Inactive, Active, and Pinned Cells
There are three hierarchical states for a cell in the grid: active and pinned, active, and inactive.
In the cell grid, one cell is active, while all of the other cells are inactive. When you pin the
active cell, it remains active when you click another cell in the grid. If no cell is pinned, the
active cell is the last cell acted on by a mouse action.
Table 3 describes the three cell states.
Table 3. Cell states

Description
You can identify the active and pinned cell by its light gray border and the green
background behind its pinned pin icon. A pinned cell is an active cell that cannot be
made inactive by clicking another cell. Instead, actions performed in the inactive cells
affect the pinned cell.

Identifying Inactive, Active, and Pinned Cells
 To make a cell active or active and pinned
Tip Clicking a cell’s pin icon is the only action required to make a cell active and
pinned. Making a cell active (but unpinned) can take up to two actions. If another
cell in the grid is active and pinned, you must first unpin it, and then click the target
cell to make it active (but unpinned).
Because you can work both directly and interactively with an active and pinned cell,
there is no advantage to making a cell active rather than active and pinned. So for
practical reasons, make the cell that you want to modify an active and pinned cell.
Do one of the following:
• If the current active view is pinned, click its pin icon to unpin it. Then, click
anywhere in the cell that you want to make active.
The selected cell is active (but unpinned). You can modify its contents by using a
menu bar command, shortcut menu command, or toolbar button.
–or–
• Click the pin icon of the cell that you want to make active.
The selected cell is active and pinned. You can modify its contents by using a menu
bar command, shortcut menu command, or toolbar button. You can also modify its
contents by working interactively in other views.
 To access the active cell’s shortcut menu
Right-click in the active cell.
With chromatogram or spectrum views containing more than one plot, any menu operations
target the active plot, indicated by a shaded background. To select an individual plot in a
multi-plot cell, click it.

Using the Cursor
Using the Cursor
Within the chromatogram and spectrum views, use the cursor in three ways:
• To select a point on the view, click the point.
• To select a range, drag a line parallel to any axis.
• To select an area, drag a line in any diagonal direction.
When you place the cursor within the graphic region of a chromatogram, spectrum or map
view, the cursor becomes a cross hair. The status bar at the bottom of the Qual Browser
window shows the coordinates of the cursor in appropriate units for the view. For example,
in a spectrum view the status bar shows the cursor position in terms of the mass-to-charge
ratio and intensity.
The effect of clicking or dragging the cursor in a view depends on the cell state and whether
another cell in the grid is pinned.
Cursor actions in an active cell (or active and pinned cell) scale the view according to the
dimensions of the dragged line or area (see Table 4).

Qual Browser displays chromatograms and spectra in a grid of cells. These topics describe the
commands used to manipulate cells:
• Making a View Active
• Inserting and Deleting Cells
• Adjusting Cell Size
• Amplifying Regions of a Plot
• Adding Text to a Plot
• Adding Graphics to a Plot
• Removing Text and Graphics from a Plot
• Opening or Changing Views in Cells
• Scaling a Plot
Note You can work directly within an active but unpinned cell. However, because there is
no advantage to making a cell active rather than active and pinned, the procedures in this
section instruct you to select the active cell by clicking its pin icon.
Making a View Active
The active cell contains the active view. There can only be one active view at a time. The
active view can be active (but unpinned) or active and pinned.
Tip There is no advantage to making cells active rather than active and pinned. So to
make a cell active, click its pin icon. The cell becomes active and pinned.
 To make a view active or active and pinned
Do one of the following:
• If the current active view is pinned, click its pin icon to unpin it. Then, click
anywhere in the cell that you want to make active.
The selected cell is active (but unpinned). You can modify its contents by using a
menu bar command, shortcut menu command, or toolbar button.
–or–
• Click the pin icon of the cell that you want to make active.
The selected cell is active and pinned. You can modify its contents by using a menu

Use the Qual Browser window to open a raw file (.raw), a sequence (.sld), or a result file (.rst).
With raw files, opened individually or from a sequence, you can create a grid of interactive
cells and display information from the raw file in any of the cells. From this display, you can
use menu commands to select display options or use the cursor to select regions of interest.
A result file contains the list of detected peaks from the chromatogram and the qualitative
processing results associated with each peak. Qual Browser displays the result file in a fixed,
two-cell arrangement. Many of Qual Browser's features are not available for use with a result
file because the raw file is not available for processing.
You can view a chromatogram, spectrum, map, spectrum list, scan header, scan filter, tune
method, processing method sample information, status log, or error log from the current raw
file in any of the cells that appear in the Qual Browser window. With chromatogram,
spectrum, and map views, you can display up to eight plots in each cell. You can use the
cursor and mouse to select points, ranges, or filters within a view. Cursor actions are always
directed toward the active cell.

Selecting a Point on a Plot
You can use Qual Browser to do the following:
• Use a chromatogram to generate a mass spectrum (incorporating single or averaged scans,
with background subtraction if required) or maps with specific time ranges.
• Use maps to generate a single or averaged spectrum or mass chromatograms with specific
mass or time ranges.
• Use a spectrum to generate mass chromatograms.
• Apply scan filters to chromatograms using the drag-and-drop method.
Selecting a Point on a Plot
The following procedure describes how to work interactively with an inactive view and an
active and pinned view to display a point of interest in the active and pinned view. For
example, you can use this procedure to display the spectrum in the active and pinned view for
a particular time point in a chromatogram (inactive view).
Note Working interactively with views requires pinning the view that you want to modify.
 To select a point on a plot
1. To activate the cross-hair cursor and status bar, move the cursor to the graphic region of a
plot. This is the region above the X-axis and to the right of the Y-axis.
The data system displays a cross-hair cursor (+) and the coordinates in appropriate units
for the display in the status bar at the bottom of the Qual Browser window.
For example, this information appears in the status bar:
• Chromatogram view: Time, Intensity
• Spectrum view: Mass (m/z), Intensity
• Map view: Time, Mass (m/z)
The data system only displays the cross-hair and status bar when a view can be used to
pick a point, range, or scan filter for application to a plot in the active view.
2. To use the cursor to determine the coordinates of a peak, position the cross-hair cursor on
the point on the plot. The application provides the X-axis and Y-axis coordinate values.

Selecting a One-Dimensional Range on a Plot
You can select a one-dimensional range in an active plot by dragging the cursor horizontally or
vertically across the plot. However, to interactively change the range displayed in one view by
selecting a point or range in another view, you must pin the view that you want to modify.
 To select a one-dimensional plot range
1. To activate the cross-hair cursor and status bar, move the cursor to the graphic region of a
plot. This is the region above the X-axis and to the right of the Y-axis.
The data system displays a cross-hair cursor and the coordinates in the appropriate units
for the view in the status bar at the bottom of the Qual Browser window.
This information appears in the status bar of these views:
• Chromatogram view: Time, Intensity, Filter
• Spectrum view: Mass (m/z), Intensity
• Map view: Time, Mass (m/z)
The data system only displays the cross-hair and status bar when a view can be used to
pick a point, range, or scan filter for application to the active view.
2. To use the cursor to redraw the active plot using the selected range of axis values, place the
cross-hair cursor at the beginning of the desired range in the active plot, and then drag the
cursor to the end of the range.
Figure 17 and Figure 18 demonstrate this selection process.

Conversely, for fragment ions of even or odd molecular weight, specify the reverse; that is,
specify odd or even, respectively, in the Nitrogen-Rule list.
McLafferty states the Nitrogen Rule as follows: “If an odd-electron ion contains no (or an
even number of ) nitrogen atoms, its molecular ion will be at an even mass
number...[Similarly,] an odd-electron ion will be at an odd mass number if it contains an
odd number of nitrogen atoms.”
Mass Tolerance
Specify a mass tolerance to restrict the number possible elemental compositions. The data
system returns results of the elemental composition search only if the computed formula
matches the entered mass within the specified tolerance. The value must be between 0.00
and 1000.00.
Units
View the units that you can associate with mass tolerance: amu (atomic mass units), mmu
(millimass units), and ppm (parts-per-million).

D = 1 + ---------------------------------------2
where
D is the value for the RDB
imax is the total number of different elements in the composition
Ni is the number of atoms of element i

The calculation results in an exact integer such as 3.0, indicating an odd-electron ion, or
an integer with a remainder of 0.5, indicating an even-electron ion. A value of –0.5 is the
minimum value and corresponds to a protonated, saturated compound (for

These peaks are labeled: (Parent Mass) PM MS2 and PM MS3.
• Normalized spectrum
When the Normalize Composite Spectrum check box is active on the MSn page of
the Info bar, each MSn spectrum is individually normalized (NL) so that its highest
peak is displayed at Relative Abundance 100. The relative peak heights of this
display are therefore not meaningful. For example, a composite spectrum (CMP) for
an MS3 experiment displays both the MS2 base peak and the MS3 base peak at
Relative Abundance 100 and maintains all other relative abundances of the other
ions in each spectrum. Use this display normalization option to view multiple
spectra simultaneously, even if the absolute value of the intensities are significantly
different.
An example follows for a process filter for a normalized composite spectrum of an
MS3 experiment in which four microscans were averaged. The parent mass of the
MS1 experiment is m/z 1108.16 and the parent mass of the MS2 experiment is
m/z 775.98. The relative collision used was 30 percent:

Average Spectrum
Description
View a spectrum that is the sum of all of the microscans taken for a particular MSn
experiment. An average spectrum can be independently displayed for MS2, MS3, MS4,
MS5, …MS10 experiments. The average spectrum is displayed normalized (NL) to the
average base peak.
In the event that there is only one spectrum with one scan to average, the Xcalibur data
system displays the term single spectrum instead of average spectrum. In other words,
single spectrum is a special case of average spectrum.
An example of a processing filter for the average spectrum of an MS3 experiment in
which two microscans were averaged follows. The parent mass of the MS1 experiment is
m/z 1108.07 and the parent mass of the MS2 experiment is m/z 776.03:

This option results in a composite of individual spectra (MS2, MS3, MS4, and so on),
normalizing each spectrum to the highest intensity in the MS2 experiment, not using
the relative number of counts. This option provides easy comparison of MSn
experimental data. However, the Xcalibur data system does not retain the peak ratio of
the MSn data.
Clear this check box if you do not want to normalize the composite spectrum displayed

Events that are listed with Initial Values cannot be changed.
The data system provides these events:
Start/End Threshold: Directly related to the RMS noise in the chromatogram, this
value is Threshold, the fundamental control used for peak detection.
Bunch Factor: The Bunch Factor is the number of points grouped together during
peak detection. It controls the bunching of chromatographic points during integration
and does not affect the final area calculation of the peak. The Bunch Factor must be an
integer between 1 and 6; a high bunch factor groups peaks into clusters.
Area Threshold: Controls the area cutoff. The application does not detect any peaks
with a final area less than the area threshold. This control is in units of area for the data.
P-P Resolution: The peak to peak resolution threshold controls how much peak
overlap must be present before two or more adjacent peaks create a peak cluster. Peak
clusters have a baseline drop instead of valley to valley baselines. This option is specified
as a percent of peak height overlap.
Negative Peaks: Automatically resets after a negative peak has been found.
Tension: Controls how closely the baseline should follow the overall shape of the
chromatogram. A lower tension traces the baseline to follow changes in the
chromatogram more closely. A high baseline tension follows the baseline less closely
over longer time intervals. Set a value in minutes.
Tangent Skim: For fused peaks that are significantly different in size, the tangent skim
method provides a method of allocating area to the various peaks. By default, the
application chooses the tallest peak in a cluster as the parent (solvent). You can also
identify which peak in the cluster is the parent. The application detects tangent skim
peaks on either side (or both sides) of the parent peak. Tangent skim automatically
resets at the end of the peak cluster.
The Threshold and Bunch Factor parameters are the most important ones in
controlling peak detection.

Description
New
Place the simulated spectrum in a new view.
Insert
Place the simulated spectrum above the selected (highlighted) spectrum.
Select a spectrum to make the Insert button active.
Replace
Replace the selected (highlighted) spectrum with the simulated spectrum.
Select a spectrum to make the Replace button active.
Chemical Formula
Enter or select the chemical formula for the simulated spectrum. Then, click the Insert or
Replace button to display the spectrum. The maximum molecular weight for the formula is
less than 600,000 amu.
You can enter both upper and lower case letters, however the Xcalibur data system interprets
all lower case input as two-letter symbols. For example, the string inau will be parsed as
In Au. You can force other interpretations by being more specific in capitalization, namely
INAu or INaU. The application interprets all upper case input as single-letter element
names. For example, COSI is interpreted as C O S I.
Specify a specific isotope by naming it in the following fashion: [13]C using square brackets
about the isotope mass number.
You can specify mixtures of substances by using additional symbols + (addition) and *
(multiplication). Both symbols are required to specify a mixture. A valid mixture has the
format substance*quantity + substance* quantity, for example, C4H8*2+H2O*5.

Change Mixture
Specify the compounds and amounts you want to include in the mixture in the
Change Mixture for Simulation dialog box. Click the Change Mixture button to open
the Change Mixture for Simulation dialog box.
Adduct
Adduct
Specify that the simulated spectrum is an adduct.
The Spectral Simulation feature in the Xcalibur data system supports two general modes of
ionization: addition or subtraction of protons and addition/subtraction of electrons.
If you clear the Adduct check box, the data system calculates the mass to charge ratio based
on the loss or addition of electrons according to this general formula:
formula mass – (sign of charge * the number of charges * electron mass) / number of charges
If you select the Adduct check box, the data system calculates the mass to charge ratio based
on protonation/deprotonation according to this general formula:
formula mass + (sign of charge * the number of charges * proton mass) / number of charges
When a formula does not contain any hydrogen atoms, the system does not subtract the
mass of a proton even though the you select the Adduct check box. See Concentration
below for more information on how the data system calculated the mass to charge ratio for
multiply charged ions when an adduct without any hydrogen atoms is selected.

Parameter
Description
Identity
Select the adduct for the simulated spectrum. Choose from H, K, or Na.
Concentration
There are four possibilities for how the adduct is added to the ion:
• one adduct:
For positive charge states and positively charged adducts, the Xcalibur data system
creates the specified charge state by adding the positive adduct for the first charge and
H+ ions for subsequent charges. For example, a charge distribution of Most
abundant=2 and Half width = 2 (2,2) and a K+ adduct shows these ions:
+1 C10K+
+2 C10HK+2
+3 C10H2K+3
+4 C10H3K+4
For negative charge states, each charge state shows loss of H+ to attain the specified
charge. If the molecule does not contain hydrogen, nothing is removed. For example,
for 2 ions C6H6 and C4 and a K adduct, the (–2,2) charge state gives:
–1 C6H5K– C4K–
–2 C6H4K–2 C4K–2
–3 C6H3K–3 C4K–3
–4 C6H2K–4 C4K–4
The second and third cases produce a distribution of adducts for charges where the
absolute values are greater than 1. It is possible to specify both a distribution of charge
states and a distribution of adducts. This case can result in an extremely complicated
spectrum when the adduct distribution overlaps the charge state distribution.
• low: the ion with no adduct will be included at 100% intensity, 1 adduct at 25%
intensity, 2 adducts at 11% intensity, and so on. (To the limit of the charge
distribution.)
• high: the ion with N adducts are included at 100% intensity, N-1 adduct at 25%
intensity, N-2 adducts at 11% intensity, and so on, where N is the absolute value of the
maximum charge simulated. (To the limit of the charge distribution.)
• 100%: the ion of charge N contains M adducts (where M is the absolute value of N.)
Charge Distribution
Charge Distribution
Specify limits on charge distribution. Change the values of the settings to simulate the effect
on ions. See Adduct for more information.
Most Abundant
Select the most abundant charge of the ion, and the data system calculates the masses
accordingly. The range will be –99 to +99, and the default value is +1.

Description
Half Width
Simulate the number of additional charges on each side of the most abundant. Select a value
from 0 to 99.
For example: If you simulate charge 10 and a half width of 3, then the data system draws
charges 10 +/- 3, giving 7, 8, 9, 10, 11, 12, 13 (with the largest peak at charge 10).
If you simulate charge 2 and a half width of 3, then the application draws positive charges
from the range 2 +/- 3, giving 1, 2, 3, 4, 5. (with the largest peak at charge 2).
If you simulate charge 1 and a half width of 3, then the application draws charges 1, 2, 3, 4.
To simulate an intensity distribution, the peaks at the edge of the distribution are shown at
5% of the height of the most abundant peak.
Output Style
Output Style
Select how you want the data system to display the simulated spectrum. The options are
pattern, profile, and centroid.
Pattern
Plot the exact pattern of isotopic peaks generated by the simulation.
Profile
Plot the pattern spectrum convolved with a gaussian, cosine, triangular, or Lorentzian
broadening function (see below). Use the Samples Per Peak box to specify the number of
data points across the peak.

Parameter
Description
Samples/Peak
Set the Samples Per Peak to the number of data points across the width of the peak.
The peak definition depends on which valley option you selected:
• FWHM: the width of the peak is measured at 50% height
• 10% Valley: the width of the peak is measured at 5% height
• 5% Valley: the width of the peak is measured at 2.5% height
After resolving 2 peaks, the data system creates a valley by the sum of the signals from the
newly resolved peaks, so the peak height of each contributing peak at the valley bottom is
half of the valley height.
Centroid
Select this option to apply the same algorithm used in the firmware to convert from
profile data to centroid. When you select centroid, both the Samples/Peak box and the
Choose Algorithm button become active.
Choose Algorithm
Select a centroiding algorithm.
Resolution
Specify the type of unit for peak width to associate with the value in the adjacent boxes. You can select resolution in
Daltons, parts per million (ppm), or resolving power. Simulate MS results from a quadrupole detector with a fixed
mass peak width (Daltons), or simulate results from a magnetic sector detector with a relative mass peak width
(ppm or resolving power).
Daltons
Specify a value for simulated peak width in Daltons. When you select the option, the box
becomes active.
PPM
Specify a value for simulated peak width in parts per million. When you select the option,
the box becomes active.
Resolving Power
Specify the resolving power for simulated peak width. When you select the option, the box
becomes active.
Resolving power is a measurement of the ability of a mass spectrometer to resolve close
peaks. For example: A resolving power of 1000 at 10% valley implies that if there are 2 equal
height peaks at mass 1000 and 1001, then there will be a valley between those peaks at
10% of the peak height, at mass 1000.5 (and that at 999.5 and 1001.5 the profile will be at
5% of the peak height).
Valley
FWHM
Select this option to make the peak width at half maximum equal to the resolution. For
example, if you select a resolution of 1 Dalton, then the peak is 1 Dalton wide at half
maximum.
10%
Select this option to simulate a valley at 10% height between just resolved peaks.
5%
Select this option to simulate a valley at 5% height between just resolved peaks.

Choose Centroiding Algorithm Dialog Box
Use the Choose Centroiding Algorithm dialog box to choose which algorithm the Xcalibur
data system uses to calculate the centroid of profile data and to specify values of parameters
used by the centroiding algorithm.
Table 52. Choose Centroiding Algorithm dialog box parameters
Parameter
Description
Centroiding Algorithm Choose which algorithm the Xcalibur data system uses to convert the simulated spectrum
from profile data to centroid data.
Choose the algorithm associated with the mass spectrometer whose spectrum you want to
simulate. Your choices are:
• LCQ/TSQ/Quantum/ICIS
• DSQ/PolarisQ/GCQ
• Valley Detection (default)
Measure Resolution At Specify where to measure the resolution of a peak. The valley detection algorithm can
measure the resolution of each peak (resolving power) by determining when the signal
crosses a threshold on both sides of the peak. The data system measures the threshold
relative to the apex height of the peak.
This option is available only when you are using the Valley Detection algorithm.
Noise Filter
Noise Filter
Check this box to turn on a filter to reject noise on peaks and prevent splitting peaks with a
dip in the peak apex.
A moving mean filter is applied to the signal, averaging the indicated number of points. The
filter is repeatedly applied, as set by the Repeat parameter.
This filtered data is only used to determine the start and end points of peaks. After this has
been determined, peaks are centroided from the original (unfiltered) signal.
For example: If peaks are being split at the apex, turn on filtering, and increase the points
value until peaks are no longer split.
Points
The number of points to consider in filtering. The value must be between 3 and 99.
Repeat
The repeat count to use in filtering. The value must be between 1 and 9.
Other
Merge Width
Merge data points that are within this range. The value can be between 0.0 and 100.0.

Peak Purity Dialog Box
Use the Peak Purity dialog box to specify the values of the peak purity parameters to be
applied to PDA raw data in an active chromatogram view.
The Peak Purity command in the Actions menu becomes active only when you open a raw file
that contains scan data (for example, PDA data) in Qual Browser and select the PDA
Detector Type from the Chromatogram Ranges Dialog Box.
Table 75. Peak Purity dialog box parameters
Parameter
Description
Enable
Turn on Peak Purity parameters for PDA chromatograms in an active chromatogram cell
and calculate peak purity results by selecting the Enable check box. Peak detection occurs
automatically before the peak purity calculation.
Scan Threshold
Specify a minimum value of intensity for wavelength scans in microabsorbance units (μAU).
Peak Purity computation using scan threshold starts with the scan at the apex of the peak
and collects wavelength data from scans on both sides of the apex until the scan threshold is
reached. Use scan threshold for either symmetrical or asymmetrical peaks.
The default value for scan threshold is 3000 μAU. The range of possible values is 0 to
1000000 μAU (or 1 AU). In a sample with high background or noise, you might start with
a value for scan threshold of 40000 μAU.
Peak Coverage
Specify a maximum percent value of the width of the integrated peak. Peak Purity
computation using peak coverage starts with the scan at the apex of the peak and collects
wavelength data from scans on both sides of the apex until the percent peak coverage is
reached. Use peak coverage for symmetrical peaks.
The default value for peak coverage is 95% of the integrated peak width.
Limit Scan Wavelength Activate the Wavelength Range box. Select this check box to limit the number of
wavelengths to include in the Peak Purity computation. Then, enter a range in the
Wavelength Range box.
Wavelength Range
Specify a range of UV scans (in nanometers) that include the wavelengths of your peak(s) of
interest. Peak Purity computation using wavelength range starts with the scan at the apex of
a peak; and then collects wavelength data from scans on both sides of the apex until all the
wavelengths in the range are included. Use wavelength range for either symmetrical or
asymmetrical peaks.
The default wavelength range is the full width of the scan. This box is available only if you
select the Limit Scan Wavelength check box.

smoothing. Select an odd number for the number of smoothing points. To change the
number of smoothing points, type the new number of points in the Points box.
Baseline Subtraction
Baseline Subtraction
Apply baseline subtraction to all chromatogram plots in the active view. This algorithm fits
a smooth curve through the noise in the chromatogram, then subtracts this curve from the
chromatogram, leaving the peaks on a flat baseline.
Enable
Activate Baseline Subtraction to chromatograms in the active cell. To turn on baseline
subtraction, select the Enable check box.
Polynomial Order
Specify the degrees of freedom allowed to the fitted curve. With polynomial order set to 0, a
horizontal straight line is fitted. With polynomial order set to 1, a sloping straight line is
fitted. The further the background is from a straight line, the higher you must set the
polynomial order control. Too high a value will cause the fitted curve to begin to follow the
peak shapes. Normal operating range for this parameter is 3 to 20.
With higher order polynomials, background subtract will sometimes have difficulty
converging on a solution. There is a pre-set upper limit of 300 iterations. If background
subtract does not seem to be making progress, press the Cancel button in the status box and
try again with a lower-order polynomial.
Below Curve
Move the background curve up and down in the noise. The curve fit is constrained to place
the specified percentage of data points beneath the fitted background curve. Normal
operating range for this parameter is 5% – 30%, depending on the abundance and width of
peaks in the chromatogram. For more or wider peaks, increase the value.
Tolerance
View the precision level for performing internal arithmetic. It should not normally be
altered from its default value of 0.01.

Mass Tolerance
Specify the value for mass tolerance. Enter a value in the range from 0.1 to 50000 and select
units to apply to the value. For a mass range chromatogram, the data system uses the
tolerance value to create the limits of a range of masses. The central mass of the range is the
one specified on the Ranges Page – Spectrum Ranges Dialog Box.
If a single mass is entered for a mass chromatogram, the data from each (filtered) scan is
analyzed in the chromatogram from mass – tolerance to mass + tolerance. If a range is
masses is entered, the limits are considered precise, and no tolerance is applied. Therefore, a
mass1–mass2 range causes data to be analyses between the exact masses entered. Use the
mass precision setting if more decimals are needed to specify masses. For base peak
chromatogram, the largest mass in the range is selected, and for mass chromatogram, the
data in the specified range is summed.

1. It discards masses without a peak maximum within ±1 scan of the defined
chromatogram peak apex.
2. It then searches for a minimum within the specified Window Size range either side of
the peak apex. These points define the peak start and peak end.
3. Using scans at and beyond the peak start and peak end, Refine measures the
background noise level in the mass chromatogram.
4. Refine uses extrapolation to estimate the contribution of noise to the scan at the peak
apex. Refine adjusts the mass intensity of the apex scan accordingly.
5. Finally, Refine uses the Noise Threshold parameter to determine whether the adjusted
intensity is significant in comparison to the background noise. If:
Adjusted Intensity < Noise Threshold × Background Noise
the mass is discarded from the final spectrum.
Enable

to the active spectrum view, select the Enable check box.
Window Size

applies the window across a chromatogram peak apex and uses it to search for the peak start

Noise Threshold
Enter a value for the Noise Threshold parameter. The Refine algorithm uses the Noise
Threshold parameter to determine whether adjusted ion intensities are significant in
comparison to the background noise. The parameter is actually a factor rather than a
threshold. For example, with a Noise Threshold value of 2, ions are discarded from the
enhanced spectrum unless their intensities are twice the measured background noise.

Description
Search Type
Use the settings in this group box to choose the type of library search applied to spectra. There are two main options:
Identity and Similarity. The difference between the two search types is primarily in the weightings of the spectrum as
a function of mass.
Identity
Apply an Identity search algorithm for library matching of spectra. A Normal Identity
search is the default option.
Normal
Apply a Normal Identity search algorithm for library matching of spectra. This is the default
option. A Normal Identity search is suited to low quality or unusual spectra. The search
algorithm uses a standard pre-screen search filter.
Quick
Apply a Quick Identity search algorithm for library matching of spectra. Use this option
when you are sure the spectrum or compound exists in the library. The search algorithm
uses a fast pre-screen search filter.
Penalize Rare
Compounds
Limit the impact of rare compounds by reducing the match factor. This option is effective
only when you have selected one or more of the NIST databases (such as MAINLIB). It has
no effect on spectra in user libraries or other commercial libraries.
Each reference spectrum in a NIST library contains a record of other commercial databases
containing information about the compound. A compound is considered 'rare' if it is
present in a limited number of these databases. If you select the Penalize Rare Compounds
option, hit compounds present in few, or no other databases other than the NIST libraries,
will have their match factors reduced (the maximum penalty is 50 out of 1000). This, in
effect, leads to a relative increase in the match factors of 'common' compounds, placing
them higher in the hit list than exotic isomers with near identical spectra. This roughly
adjusts for the so-called “a priori probabilities” of finding a compound in an analysis.
Similarity
Apply a Similarity search algorithm for library matching of spectra.
Simple
Select this option button if you want to apply a Simple Similarity search algorithm for
library matching of spectra. This option finds a large set of spectra to compare with the
submitted spectrum, and is generally slower than an Identity search.
A Simple Similarity search should be used if:
• You know that the unknown spectrum is not in the library
• The spectrum is of poor quality so that a reliable match is unlikely
Hybrid
Select this option button if you want to apply a Hybrid Similarity search algorithm for
library matching of spectra.
This option uses a combination of the Simple and Neutral Loss search strategies. As for the
neutral loss search, an estimate of the unknown’s molecular weight is required. If the
unknown compound contains chemical structures that generate both characteristic ions and
neutral loss patterns, these structures can be identified from the hit list produced by this
search.

Parameter
Description
Neutral Loss
Select this option button if you want to apply a Neutral Loss Similarity search algorithm for
library matching of spectra.
The neutral losses in a spectrum are the mass differences between the molecular ion and
other major ions in the spectrum. For certain classes of compound, neutral losses can be
very characteristic spectral features.
In a Neutral Loss search, the data system examines the submitted spectrum and identifies
the molecular ion. The application submits the mass value of the molecular ion to the search
along with the spectrum. The search algorithm calculates the significant neutral losses and
compares them with library data. Hits are returned according to matches of the molecular
ion and its neutral losses.
Options
Search With MW=
Select this check box if you want to restrict the search to library entries with a particular
molecular weight. Use the associated text box to enter the molecular weight.
Reverse Search
Select this check box to sort matching library spectra by the Reverse Search Match Factor.
By default, the data system sorts matches by the Forward Match Factor.
Mass Defect
This group box contains the parameters used in library searches that allow you to correct for the differences between
the actual masses and the nominal integer masses of the atoms in a molecule. Assign a larger value (in millimass units)
for mass defect to larger molecules because, in general, they are composed of more atoms than smaller molecules;
larger molecules need a larger correction factor to approximate the linear function that the Xcalibur data system uses
to calculate masses.
When you enable mass defect, the data system uses the parameters in library searches of spectra that you export from
the spectrum view of Qual Browser.
Enable
Include mass defect values for library searches in a processing method.

ranges in the first text box, and specify a larger value for higher mass ranges in the second

from any other selected raw file. You can use this utility to subtract a background spectrum
from a raw file or deconvolute merged or overlapping component peaks.
Table 97. Subtract Background dialog box parameters (Sheet 1 of 2)
Parameter
Description
Input
File
View or change the path name of the input raw file. You can change the source of
the input file in one of these ways:
• Click Browse adjacent to the box and browse to the required file
• Type the full path and filename of the required file into the box.
Scan Filter
View the selected scan filter to be applied to the input file. You can also use the scan
filter format to type a scan filter into the Filter combo box.
 To select a filter
1. Click the arrow on the Filter combo box to display filter options that are stored
in the raw file.
2. Select the desired filter. The data system displays the selected filter.
All Detectors
Specify that all detector data sources should be used to produce the input
chromatogram. The check box is unavailable for single source raw files.
Single Detector
Select a data source for the input chromatogram from the chosen raw file. The box
lists the detector sources recorded in the raw file.
Negative Chromatographic
Subtraction Results Allowed
Background subtraction normally enforces a rule that chromatogram data cannot
be less than zero. Normally, if background subtraction results in a negative value, it
is set to zero. However, select this check box to prevent this action from happening.
Background
File
View or change the path name of the raw file to be subtracted from the input file.
You can change the source of the background file in one of these ways:
• Click Browse adjacent to the box and browse to the required file
• Type the full path and filename of the required file into the box.
Scope
Subtract Whole File
Specify that the whole of the background file is to be subtracted from the input file.
Subtract Single Scan (RT)
Specify that a single scan from the background file is to be subtracted from each
scan of the input file. Type the number of the scan in the adjacent box.

Parameter
Description
Alignment Offset (RT)
Specify how much time, in minutes, to offset the background subtraction file.
A positive alignment offset implies that the peaks in the background subtraction
file have larger retention times than the peaks in the file it is subtracted from.
Scaling Factor
Specify a scaling factor for the subtract background file operation. Type the factor
you want to apply to the background file before its subtraction from the input file.
Output
Name
View the filename for the output file resulting from the subtraction of the
background file from the input file. The data system uses the input filename with a
BG_ prefix.
Folder
View or change the folder to store the output file after the subtract background file
operation. You can change the folder in one of these ways:
• Click the Folder button adjacent to the box and browse to the required folder
• Type the full path of the folder into the box.
Buttons
Proceed
Start the Subtract Background file operation using the settings in the dialog box.
