Onyx PCX Derivatization Instrument

Now, it is surpassed by the Onyx PCX as the best post-column instrument available on the market. Pickering Laboratories still offers the only instrumentation optimized for the analysis of Amino Acids, Carbamates, Glyphosate, Mycotoxins, Antibiotics and many other applications. Each component is specifically designed to enhance sensitivity and selectivity. Only Pickering Laboratories offers complete application support, including chemicals, columns, methods and post-column systems.

Accuracy, Durability, Speed and Convenience

Instrument layout is focused on ease of use, quick monitoring and rapid service.
The electronic syringe pump provides true pulsefree flow for superior sensitivity and consistency. The pump cylinder and head are made from a single piece of inert ceramic for durability and non-reactivity.
Electronic valves eliminate troublesome check valves and allow automated pump flushing.
Quick-change reactor cartridges make application switching easy and replacements fast and inexpensive.
The column oven utilizes circulating air for consistency of heating and quick cooling within 1 °C of setpoint.
The column oven utilizes circulating air for consistency of heating and quick cooling within 1 °C of setpoint.
The Onyx PCX control software allows for precise control of the reagent delivery and conservation.
Pre-programmed testing and maintenance procedures take the guesswork out of instrument care.
Column oven temperature gradient programming improves separation and run times. Only Pickering Laboratories builds post-column systems with this feature.
Works with any HPLC instrument, from any manufacturer.

Electronic Syringe Pumps and Valves

The syringe pump’s cylinder and head are made from a single piece of 99.9% Alumina for ruggedness and non-reactivity. The piston surface is made from PEEK with an inert O-ring seal. The piston seal is protected by an automatic piston wash system that provides long seal life. The programmable flow rates range from 50 ul to 1500 ul/minute with a refill cycle of under 60 seconds. The electronic valve utilizes PEEK and PTFA with a port layout that eliminates cross contamination.

Onyx PCX Control Software

The Onyx PCX is controlled by PCX Control Software, compatible with Windows 7 or newer Windows operating systems. Using the same computer as the HPLC, the PCX Control Software interfaces easily with Agilent OpenLab or communicates with any other modern HPLC using a relay connection.

Manifold with anti-siphon valves and two 1/4-28 fittings

Safeguards

In-line check valve prevents reagent back flow into the column when HPLC pressure drops
Replaceable reagent filters to prevent reactor fouling
Post-column system over-pressure protection from pre-calibrated relief valve opens at 500 psi (35 bar) to prevent rupture of the post-column reactor tubing in the event of down-stream blockage
Back-pressure regulator applies 100 psi (7 bar) to the detector flow cell outlet (waste line) to prevent detector noise and precipitation due to out-gassing or boiling
