HPLC POST-COLUMN DERIVATIZATION | INSTRUMENTS / COLUMNS / METHODS / REAGENTS
THE CONVENTIONAL WISDOM SAID IT COULDN’T BE DONE. BUT PROFOUND
NAIVETÉ LED ME TO THINK “HOW COULD I NOT SUCCEED.” WE THEN SET ABOUT
REVOLUTIONIZING AMINO ACID ANALYSIS.
Previously you could do amino acid analysis only with a dedicated amino acid analyzer which has almost no fl exibility. We developed
an eluant/column combination and the hardware necessary to transfer the analysis to a modern gradient HPLC. The result was a
method with the most fl exibility that could evolve with the hardware and thus benefi t from each generational improvement. Thus
the user may always have the benefi ts of the latest HPLC technology. Even today, dedicated amino acid analyzers execute the
same method as when introduced in the late 50’s.
MICHAEL V. PICKERING, PH.D. / FOUNDER
As we enter a new decade, I am drawn back to the beginning. After I finished two postdoctoral positions in medicinal
chemistry, I worked four years in R&D at two different HPLC instrument companies. During that time, I came
01
to the realization that the end user does not want capital equipment, solvents, chemicals, or computers. They want
reliable chromatograms.
As Aristotle’s theory on causality teaches, the final cause comes first. In this instance, the final chromatogram drives
the user’s choice for equipment and chemistry. So convinced was I of this truth, I jumped into the void of self-
employment. Our product would be the ethereal “Guaranteed Chromatography.” I started Pickering Laboratories
in 1980, with the patented ninhydrin reagent TRIONE®. Soon thereafter we began offering gradient Amino Acid
Analysis methods that were achievable with modern HPLC equipment.
Back then, Amino Acid Analysis run times were 140-minutes for Lithium cation-exchange (native fluid analysis) and
90-minutes for Sodium cation-exchange (hydrolysate analysis). Today, the same chromatograms are achievable in
70-minutes for Lithium and 30-minutes for Sodium.
As you are all aware by now, we work hand in hand with the AOAC, FDA, USDA and USEPA. The relationships
we’ve cultivated over the years with these regulatory agencies have enabled us to influence analytical methods as they
develop, and to better understand and support you. In the same context, we are regularly invited to make custom
formulations and develop pharmaceutical QC methods.
Our contribution to these regulatory agencies was recently recognized in September of 2009, at the 125th Anniver-
sary meeting of the AOAC International in Philadelphia. Pickering Laboratories received AOAC’s Single Labora-
tory Validation of the Year Award for Multiresidue Mycotoxin Analysis in Corn Grain by High-Performance Liquid
Chromatography with Post-column Photochemical and Chemical Derivatization. Several colleagues and I attended
the award ceremony – it was an honor for Pickering Laboratories. In fact, the award was doubled to include our
Single-Laboratory Validation for the Quantification of Neomycin B and Neomycin C in Animal Feeds by Liquid
Chromatography Fluorescence Detection with Post-column Derivatization.
Well, here we are, 30 years later. My belief in Aristotle’s theory has turned out to be true. The relationship we have
created has knit us together as a team: you observe/we support.
A new range of products is presented in this catalog, so I encourage you to scan it for a solution for your needs. Or,
call and ask for our advice.
Your loyalty is our greatest reward.

PINNACLE PCX DERIVATIZATION INSTRUMENT
Part of the complete integrated system of instruments, chemicals, columns, methods and support from
Pickering Laboratories.
The Pinnacle PCX Sigma Series is an optimized HPLC post-column derivatization system for analysis of Amino Acids,
Carbamates, Mycotoxins, Antibiotics and many other applications. This instrument is the culmination of Pickering
Laboratories’ 30 years of experience in post-column analysis instrument manufacturing. Each component is specifi cally
designed to optimize the sensitivity and selectivity of post-column analysis.
Only Pickering Laboratories offers the complete package of chemicals, columns, methods and post-column systems.
Because each part of the method is designed to work together, Pickering Laboratories can offer the extraordinary
promise that the analysis is guaranteed to work for the intended application.
The Pinnacle PCX refl ects the ease of use, reliability and ruggedness you have come to expect from
Pickering Laboratories.
SYSTEM DESIGN ADVANCEMENTS RESULT IN OPTIMIZED ANALYSIS:
• The electronic syringe pump provides true pulse-free fl ow for superior sensitivity and consistency. The pump
cylinder and head is made from a single piece of inert ceramic for durability and non-reactivity.
• Electronic valves eliminate troublesome check valves and allow automated pump fl ushing.
• The quick-change reactor cartridge makes application switching easy and replacements quick and inexpensive.
• The column oven utilizes circulating air for consistency of heating and quick cooling.
• Inert fl ow path extends system life and reduces maintenance.
• The PCX control software allows for precise control of the reagent delivery and conservation.
• Column oven temperature gradient programming improves separation and run times. Pinnacle PCX is the only
post-column system with this feature.
• Works with any HPLC system.
• RoHS compliant

FEATURE HIGHLIGHT
The Pinnacle PCX has a column oven capable of programmable temperature gradients. This feature is useful in Amino
Acid Analysis by enabling additional fl exibility when optimizing methods. Using the temperature gradient program allows
for improved separation, shortened analysis time and fi ne-tuned methods for specifi c compound detection.
The Chromatogram in Figure 1 demonstrates some of the clear advantages of the temperature gradient program. Com-
pared to the standard method without the temperature gradient the total run time is 42 % shorter. Additionally, separation
is improved.
With the temperature gradient program, you are able to focus on different areas of the chromatogram for your specifi c
compound of interest.
