Onyx PCX Launch – Press Release


Next generation post-column derivatization instrument delivers on promise of “Guaranteed Chemistry”

Mountain View, California, Nov 25, 2019 – Environmental, pharmaceutical and feed laboratories now have access to the newest model of post-column derivatization instruments – the Onyx PCX.  Every component of this system has been optimized for post-column applications, thereby improving ease of use, reliability and ruggedness of analytical instrumentation. Onyx PCX is used in the analysis of amino acids, glyphosate, mycotoxins, antibiotics, cannabinoids and a variety of other applications. This latest instrument is part of the commitment Pickering Laboratories has to complete application support. Together with analytical columns, high-purity reagents, mobile phases and methods, the Onyx PCX post-column system supports Pickering Laboratories’ guarantee of method performance and chromatographic separation.

The Onyx PCX features a precisely programmable convectional column oven with temperature gradient capabilities and a fully inert flow path with ceramic syringe reagent pumps, PEEK electronic valves and PTFE reactor coils. All main components of the system are accessible from the front panel for ease of monitoring and maintenance. Following the tradition of Pickering Laboratories’ derivatization instruments, the Onyx PCX can be connected to any HPLC system, greatly expanding the LC’s capabilities.

“We are also very excited about new software features, such as extensive record-keeping capabilities and automated heaters calibration,” says Dr. Maria Ofitserova, Senior Research Chemist at Pickering Laboratories. “In addition to log files collecting real-time data on all instrument parameters for troubleshooting purposes, we now have the User Journal that allows laboratories to maintain records of completed runs, error messages, changes to methods and sequences.” She continues, “these and other details are important for audits and regulatory compliance. We also introduced an automated calibration feature for our heaters, which supports instrument performance qualification in the field.”
