with your moisture analyzer:
$ Contact your local Denver
Instrument office, dealer or
service center
– Flammable or explosive
substances
– Substances that release flammable
or explosive gases or vapors
during the drying process
In some cases, it is possible to
operate the moisture analyzer in an
enclosed nitrogen atmosphere to
prevent the vapor released during
drying from coming in contact with
oxygen in the surrounding atmosphere. Check on a case-to-case basis
whether this method can be used,
because installation of the analyzer
in too small an enclosed space can
affect its functions (for instance,
through excessive heat build-up
within the analyzer). When in doubt,
perform a risk analysis.
The user shall be liable and responsible for any damage that arises in connection with this moisture analyzer.
Poisoning
Warning: Severe Burns!
– When setting up the moisture analyzer, leave enough space to prevent heat from building up and to
keep your analyzer from overheating:
– leave 20 cm (about 8 inches)
around the moisture analyzer
– leave 1 m (3 ft.) above the device
– Do not put any flammable substances on, under or near the
moisture analyzer, because the
area around the heating unit will
heat up
– Be careful when removing the
sample from the chamber:
the sample itself, the heating unit
and the sample pan used can still
be extremely hot
– Prevent excessive heat build-up
around the analyzer
4
Explosion
– Substances that contain solvents
– Protect the moisture analyzer from
contact with liquid
! Make sure before getting started
that the voltage rating printed on
the manufacturer’s label is identical
to your local line voltage (see the
section “Connecting the Moisture
Analyzer to AC Power” in the
chapter entitled “Getting Started”)
Hazards for persons or equipment
posed by using specific samples:
Caustic burns
– Substances containing toxic or
caustic or corrosive components
may only be dried under a fume
hood. The value for the “lower
toxic limit” in a work area must
not be exceeded.
Corrosion:
– For substances that release
aggressive vapors during the
heating process (such as acids),
we recommend that you work
with small sample quantities.
Otherwise, vapors can condense
on cold housing parts and cause
corrosion.
The user shall be liable and responsible for any damage that arises in connection with this moisture analyzer.
Getting Started
The moisture analyzer consists of a
heating unit, a weighing system, and
a display and control unit. In addition
to the socket for AC power (mains
supply), it also has an interface port
for connecting peripheral devices,
such as a PC, an external printer, etc.
Equipment Supplied
The equipment supplied includes the
components listed below:
Storage and Shipping Conditions
Allowable storage temperature:
0 ...+40°C (+32°F...+104°F)
– Pan support
Do not expose the moisture analyzer
unnecessarily to extreme temperatures, moisture, shocks, blows or
vibration.
– Dust cover for keypad
Unpacking the Moisture Analyzer
§ After unpacking the moisture analyzer, check it immediately for any
visible damage as a result of
rough handling during shipment
– 1 pair of forceps
$ If any sign of damage is visible,
proceed as directed in the chapter
entitled “Care and Maintenance,”
under the section on “Safety
Inspection”
It is a good idea to save the box and
all parts of the packaging until you
have successfully installed your
moisture analyzer. Only the original
packaging provides the best protection for shipment. Before packing
your moisture analyzer, unplug all
connected cables to prevent damage.
– Moisture analyzer
– Power cord
– Pan draft shield
– 80 disposable aluminum sample
pans
Installation Instructions
The moisture analyzer is designed to
provide reliable results under normal
ambient conditions in the laboratory
and in industry. When choosing
a location to set up your moisture
analyzer, observe the following so
that you will be able to work with
added speed and accuracy:
– Set up the moisture analyzer on
a stable, even surface that is not
exposed to vibrations, and level
it using the four leveling feet
Conditioning the Moisture Analyzer
Moisture in the air can condense
on the surfaces of a cold moisture
analyzer whenever it is brought into
a substantially warmer place. If you
transfer the moisture analyzer to a
warmer area, make sure to condition
it for about 2 hours at room temperature, leaving it unplugged from AC
power. Afterwards, if you keep the
moisture analyzer connected to AC
power, the continuous positive difference in temperature between the
inside of the moisture analyzer and
the outside will practically rule out
the effects of moisture condensation.
Setting up the Moisture Analyzer
§ Position the components listed
below in the order given:
– Dust cover over the keypad
– Pan draft shield
– Pan support; turn to the left or
right, press slightly until it stops
and snaps into place
– Disposable sample pan
– Avoid placing the analyzer in close
proximity to a heater or otherwise
exposing it to heat or direct sunlight
– Avoid exposing the moisture
analyzer to extreme temperature
fluctuations
– Protect the moisture analyzer from
drafts that come from open windows or doors
– Keep the moisture analyzer
protected from dust, whenever
possible
– Protect the moisture analyzer from
aggressive chemical vapors
– Do not expose the analyzer to
extreme moisture
– Make sure to choose a place
where excessive heat cannot build
up. Leave enough space between
the moisture analyzer and materials that are affected by heat.

Basics of Moisture Analysis
Purpose
The IR moisture analyzer can be used
for quick and reliable determination
of the moisture content of materials
of liquid, pasty and solid substances
using the thermogravimetric
method.
Material
The moisture of a material is often
mistakenly equated with its water
content. In fact, the moisture of a
material includes of all the volatile
components which are given off
when the sample is heated, no matter the kind of material. Among such
volatile substances are:
When deductive methods are used,
the moisture content is indirectly
determined. A physical property
related to the moisture in the substance is measured (e.g., absorption
of electromagnetic rays).
These methods include Karl-Fischer
titration, infrared spectroscopy,
microwave spectroscopy, etc.

Thermogravimetry is the process
of determining the loss of mass that
occurs when a substance is heated.
In this process, the sample is
weighed before and after being heated, and the difference between the
two weights determined is calculated.
water
fats
oils
alcohols
organic solvents
flavorings
products of decomposition
(when a sample is overheated)
There are many methods for determining the moisture content of a
substance. Basically, these methods
can be divided into two categories:
absolute and deductive methods.
When absolute methods are used,
the moisture content is directly
determined (for example, as a weight
loss registered during the drying
routine). These methods include
oven drying, infrared drying, and
microwave drying. All three of these
methods are thermogravimetric.
In a conventional drying oven,
circulating hot air warms the sample
from the outside toward the inside.
Efficiency is lost during drying
because as the moisture evaporates,
it cools the sample surface.
By contrast, infrared rays (IR rays)
penetrate a sample without being
impeded. Having reached the interior
of a sample, they are converted into
heat energy, which stimulates evaporation, thus drying the sample.
IR rays
IR-Strahlung
Wärmeenergie
thermal energy
Substanz
substance
19
A small part of the IR rays is reflected
from the surface of the substance.
The quantity of reflected IR rays
depends to a great extent on whether
the substance is light or dark-colored.
When preparing a substance for
analysis, you should use methods
that do not generate heat so that the
sample does not lose moisture
before it is analyzed.
Perform initial analysis of a new
substance to test how the IR rays are
absorbed by the sample and converted into heat. A printout of the intermediate values of the drying process
(see page 25) provides you with this
information at an early stage.
Dark Substance
Low Reflection
Light Substance
High Reflection
How the rays penetrate the sample
depends on the sample’s light-transmitting capacity. If the light-transmitting capacity is low, the rays can
penetrate only the uppermost layers
of the sample. The heat conductivity
of the sample dictates the degree to
which the heat can be transmitted
to the underlying layers. The higher
the conductivity, the faster and more
uniformly the substance is heated.
The substance should be applied to
the sample pan in a thin, even layer.
A height of approximately 2 – 5 mm
for 5 – 15 g substance weight has
proved to be ideal. Otherwise, the
sample will not be dried completely
or the analysis time will be unnecessarily extended, a crust/skin will form
on the surface of the sample or the
sample will scorch, and the analysis
results obtained will not be reproducible, and therefore cannot be
used.
Incorrect Application of a Sample
20
Experience has shown that the temperature setting selected for infrared
drying is usually lower than the temperature setting used when working
with a drying oven.
In many cases, the fully automatic
shutoff mode will meet your requirements. If the final result is higher or
lower than expected, try varying the
temperature setting before resorting
to a different shutoff parameter.
When analyzing samples that lose
their moisture only very slowly or
when operating a cold moisture
analyzer, the fully automatic mode
may end the drying routine too early,
if it does not detect any analyzable
progress in the drying routine
under these conditions. In this case,
preheat the moisture analyzer for
2–3 minutes before starting the
drying routine, or select a different
shutoff parameter.
– Adjustment to the available measuring system (if required)
Adjustment to an Existing Measuring System
A moisture analysis method often replaces another drying method (e.g., oven
drying method), because it is simple to use and requires shorter analysis time.
In this case, you should adapt this method to that of the moisture analyzer in
order to obtain values comparable to those yielded by your standard reference
method.
– Sample preparation
§ Perform parallel measurements: take a fresh sample and divide it in half
– Setting the drying program
parameters
§ Determine the moisture content of the first half using your standard method
of analysis
Preparation
Before drying a sample, you must
carry out the following preparations:
§ Analyze the second half of the sample in the moisture analyzer.
Use the following settings:
– fully automatic mode for the shutoff parameter
– lower temperature settings than for the oven drying method
– temperature setting for organic substances: 80–100°C
– temperature setting for inorganic substances: 140–160°C
$ If the result of the second analysis does not correspond to that of the first:
– first, repeat the analysis using a different temperature setting
– then use the semi-automatic mode for the shutoff parameter (for example,
with a different loss rate per 24 s)
$ Vary the shutoff parameter, if required:
– Increase end-point recognition: set the parameter to 2 mg / 24 s or 1 mg /24 s
– Decrease end-point recognition: set the parameter to 10 mg / 24 s or
20 mg / 24 s
21
Preparing a Sample
Selecting a Sample
§ Select a representative part of the whole substance as a sample
– a representative number of individual samples for quality control
– samples which indicate a trend are sufficient for in-process control
$ Homogenize the product before a sample is taken, if required, by:
– mixing or stirring,
– taking several samples from different areas of the product, or
– taking several samples at defined intervals
§ Take only one sample at a time for a given analysis and prepare it as quickly
as possible. In this way, it will not lose or gain moisture as a result of the
ambient conditions.
$ If you need to analyze several samples at a time, the samples must be sealed
in air-tight containers, in order to ensure that the storage conditions do not
alter the state or condition of the samples:
– Warm or highly volatile substances lose their moisture very quickly.
– If you store the samples in a container, the moisture can condense on the
walls
of the container.
– If the container is too big and not filled completely, the sample can
exchange its moisture with the air remaining in the container.
$ Mix the condensed moisture back in with a sample, if necessary.
Preparing a Sample
§ When crushing a sample, avoid any contact with heat: heat results in moisture loss.
§ Crush a sample with
– a pestle
– a shredder (see below)
For liquids containing solids, use
– a glass stirrer,
– a spoon, or
– a magnetic stirrer.
$ Use an appropriately designed tool for shredding a sample.
Using Disposable Sample Pans
§ Use only Denver Instrument disposable sample pans (inner diameter =
92 mm). Reusing sample pans leads to poor reproducibility of results for
several reasons:
– after cleaning, sample residues can still remain on the pan
– residues from cleaning agents can evaporate during the next moisture
analysis
– if scratches and grooves are inflicted during cleaning, the hot, rising air
produced during the drying process acts on these surfaces, resulting in
a more pronounced buoyancy
22
Applying a Sample to the Sample Pan
§ Apply the sample to the sample pan in a thin, even layer
(height: 2 to 5 mm, weight: 5 to 15 g); otherwise:
– a sample applied unevenly will result in a non-uniform distribution of heat
– a sample will not be dried completely
– the analysis time will be unnecessarily extended
– the sample burns or a crust/skin forms on its surface as a result of a very
thick layer
– the crust makes it difficult or impossible for moisture to escape from the
sample during the drying process
– uncertain and unknown quantity of moisture remains in the sample
§ Apply liquid samples, pasty samples or samples that can melt to a glass
fiber filter; you will obtain the following advantages:
– uniform distribution due to the capillary effect
– liquids prevented from beading together and forming drops
– with larger surfaces, the moisture can evaporate faster
– considerably more convenient than the “sea-sand method”
When drying samples containing sugar, a crust or skin can form and seal the
surface.
A glass fiber filter is especially helpful in such cases. The moisture can evaporate downwards through the surface of the filter. You can prevent or limit the
crust/ skin formation if you place the glass fiber filter on top of the sample.
§ Cover solid, heat-sensitive samples with a glass fiber filter; you will obtain
the following advantages:
– gentle heating, because of the sample surface is shielded from excessive
heat
– higher temperature setting can be selected
– uniformity of the sample surface
– fast evaporation of the moisture
– excellent reproducibility for samples containing fat
Avoiding the Formation of Crust/Skin
You can add “solvents” to the sample to prevent the formation of crust/skin
during the analysis runs. The weight of a solvent you apply to the sample will
not influence the final result of an analysis.
§ Once you have closed the sample chamber, open it again within 2 seconds
after you hear a beep tone.
§ Apply a solvent to the sample
§ Close the sample chamber and start the analysis run as usual

Calibration, Adjustment
Purpose
Calibration is the determination
of the difference between the weight
readout and the true weight (mass)
of a sample. Calibration does not
entail making any changes within
the weighing system.
Adjustment is the correction of the
difference between the measured
value displayed and the true weight
(mass) of a sample, or the reduction
of the difference to an allowable
level within maximum permissible
error limits.
Features
Calibration is performed externally
with the following weight values:
50 g (accuracy class E2)
You can have calibration and
adjustment results documented as
a ISO/GLP-compliant printout;

! Warning When Using Pre-wired
RS-232 Connecting Cables
RS-232 cables purchased from
other manufacturers often have
incorrect pin assignments for use
with Denver Instrument weighing
systems. Be sure to check the pin
assignments against the chart
on page 42 before connecting the
cable, and disconnect any lines
marked “Internally Connected”
(e.g., pin 6). Failure to do so may
damage or even completely ruin
your weighing system and/or
peripheral device.

Synchronization
Handshake
Transmitting Device:
During data communication between
the moisture analyzer and an on-line
device (computer), messages consisting of ASCII characters are transmitted via the interface. For errorfree data communication, the
parameters for baud rate, parity,
handshake mode and character format must be the same for both units.
The moisture analyzer interface has
transmit and receive buffers. You can
define the handshake parameter in
the Setup menu:
Once XOFF has been received,
it prevents further transmission of
characters. When XON is received,
it re-enables the transmitting device
to send data.
– Hardware handshake (CTS/DTR)
– Software handshake (XON, XOFF)
Receiving Device:
Hardware Handshake
You can adapt your moisture analyzer by setting corresponding parameters in the Setup menu.
If you do not connect a peripheral
device to the analyzer’s interface
port, this will not generate an error
message.
With a hardware handshake, 1 more
character can be transmitted after
CTS (“clear to send”).
To prevent too many control commands from being received at one
time, XON is not transmitted until the
buffer is almost empty.
Activating Data Output
Software Handshake
The software handshake is controlled
via XON and XOFF. When a device is
switched on, XON must be transmitted to enable any connected device
to communicate.
When the software handshake is
configured in the Setup menu, the
hardware handshake becomes active
after the software handshake.
You can define the data output
parameter so that output is activated
either when a print command is
received, or automatically and synchronously with the analyzer display.
Data Output by Print Command
The print command can be transmitted by pressing r or by sending
a software command (Esc P).
The data transmission sequence is as
follows:
Moisture

device)
__ byte __> Computer
__ byte __> (receiving

Instructions for Recycling the Packaging
To ensure adequate protection for
safe shipment, your moisture analyzer
has been packaged to the extent necessary using environmentally friendly
materials. After successful installation of the moisture analyzer, you
should return this packaging for
recycling because it is a valuable
source of secondary raw material.
For information on recycling options,
including recycling of old weighing
equipment, contact your municipal
waste disposal center or local recycling depot.
– the moisture analyzer no longer
functions properly
– the moisture analyzer has been
stored for a relatively long period
under unfavorable conditions
– the moisture analyzer has been
exposed to rough handling during
shipment
In this case, notify your nearest
Denver Instrument Service Center.
Maintenance and repair work may
be performed only by service technicians who are authorized by Denver
Instrument and who:
– have access to the required maintenance manuals
– have attended the relevant service
training courses
We recommend that the moisture
analyzer be inspected according
to the following checklist by
a qualified Denver Instrument
service technician:
– Resistance of the protective
grounding conductor < 0.2 ohm
measured with a commercially
available multimeter
– Insulation resistance > 2
megohms measured with a constant voltage of at least 500 volts
at a 500 kohm load
The duration and number of measurements should be determined by a
qualified Denver Instrument service
technician according to the particular
ambient and operating conditions.
However, such inspection must be
performed at least once a year.
