Agilent’s Electrochemistry Meters
deliver rugged simplicity
and fast, reliable data
Designed by chromatographers
for chromatographers
Chromatographers around the world rely on Agilent LC instruments and columns
for the highest quality and most reliable performance.
Now, our Agilent pH, DO, ISE, Conductivity and Multi-Parameter Meters
and electrodes continue this tradition of excellence, giving you the ease-of-use,
durability, and accurate results your analyses demand. Features such as simplified
controls, waterproof connectors, and multi-parameter measurement capabilities
make Agilent pH, DO, ISE, Conductivity and Multi-Parameter Meters your first
choice for a broad range of applications, including:
General HPLC: Use Agilent pH meters to adjust and monitor the pH of your mobile
phase for optimal LC column performance.
Environmental: Agilent pH and ISE meters meet stringent regulatory demands for
analyzing wastewater or drinking water, evaluating fresh or salt water, and monitoring
soil conditions.
Food safety: Agilent pH meters help you make sure that standards for manufacturing
and quality control are met.
Consumer products: With Agilent pH and ISE meters, you can be confident that you
are getting the accurate pH and Ion Selective Electrode (ISE) measurements you need
for formulation, QA/QC, and finished product labeling.
Pharmaceutical: You can trust Agilent pH meters to give you reliable, repeatable,
and precise pH measurements of solutions of pharmaceutical formulations.
In addition, Agilent offers a full line of electrodes that are also compatible with your
existing electrochemistry meters, so you can keep all your meters operating at peak
performance.
Developed with chromatographers in mind,
Agilent meters and electrodes apply the
same high standards we use for our
instruments and columns.

Wide range of Agilent electrodes
help meet the needs
of any application
Unlike single-layer breathable membrane electrodes, Agilent electrodes are made
from multi-layered composite materials for extra durability. They also feature a
specific barrier to protect the glass bubble against breakage.
What’s more, the unique reference system on every Agilent electrode is backed by
our uncompromising materials quality and manufacturing process – giving you fast
response and high accuracy.
The electrodes shown here use universal connections, so you can use them
interchangeably on Orion 3 star, 4 star meter, Hach HI2221 and Mettler FE20pH.

pH Management:
A key to confident chromatography
Mobile phase pH can impact the selectivity, peak shape, and retention of your
chromatography, as you will see in the chromatogram series below.

The effect of pH on resolution
Left:
Right:
Neutral samples were run at pH 3 and 7.
Note that there is little difference between
the chromatograms.
Here you can see that ionizable compounds
(acids and bases) can significantly change
retention and selectivity with changes in pH.
Always consider your detector when choosing a mobile phase modifier. Modifiers
that work well with UV detectors may not be compatible with MS detectors.
22
Selecting the right mobile phase modifier for UV detectors
Your choice of mobile phase modifier (buffer) can have a strong influence on your
detector. For UV detectors, the buffer should be effectively transparent at the wavelength
of interest, which is why buffers with UV cutoffs (below 220 nm) work best.
Special considerations for LC/MS
When working with MS detectors that have LC/MS ionization sources, it is critical
to exclude non-volatile materials from your mobile phase, (and sometimes your sample
as well). This will prevent ionization source fouling as the mobile phase is nebulized
and partially dried in the source.
Five tips for pH management
1.
Non-ionized analytes have better retention than ionized analytes. Choose a low
pH buffer for acids and a high pH buffer for bases (if feasible).
2.
Silanols on silica ionize at mid pH, increasing the retention of basic analytes
and the likelihood of ion exchange interactions. Acidic mobile phases are best
for separating ionizable compounds by reversed phase chromatography.
3.
Choose a mobile phase pH that optimizes retention and selectivity.
4.
Avoiding extreme pH values (either very high or very low) lengthens column
life. Buffers can help maintain a consistent pH, improving reproducibility.
If your method requires pH-extremes, the Agilent 1260 Infinity Bio-inert LC
system might be a good choice – it is specified for pH 1-13 (short term 14).
5.
ZORBAX Eclipse Plus HPLC columns can be used over a wide pH range (2-9).
For high pH, start with Extend-C18 or polymeric phases; for low pH, use
StableBond or polymeric phases.

Agilent’s pH Meter family reflects our ongoing commitment
to simplifying method development
Leading the way toward infinitely better chromatography
From “workhorse” LC systems for routine analysis to sophisticated, high-resolution
LC/MS instruments, Agilent’s 1200 Infinity Series combines uncompromised UHPLC
performance with a modular design for easy customization.
Setting the pace for fast LC and easy method transfer
Agilent Poroshell 120 and 300 columns give you speed and resolution that are
comparable to sub-2 µm columns – with up to 50% less backpressure, so you can get
more from every LC instrument.
Agilent ZORBAX Rapid Resolution High Definition (RRHD) columns are the only
columns stable to 1200 bar for ultimate speed and resolution.
You can also count on simple method transfer and scalability, because ZORBAX RRHD,
Poroshell 120 and 300 columns seamlessly scale to the entire ZORBAX family.
Keeping you in command of your analyses
Agilent’s meticulous production oversight ensures column and sample prep
consistency. With more than 40 years of experience producing polymers and silica
chemistries, our team is committed to continuously developing advances that make
your more productive.
