Onyx PCX        포스트 컬럼 유도체화 시스템



Onyx PCX 소개 (Introduction)2-onyx-systems-300x291.png

It’s the next generation of HPLC post-column derivatization instruments resulting from Pickering Laboratories’ 35 years of experience in post-column instrument manufacturing. Previously, the Pinnacle PCX set the benchmark for innovative design as the top-of-the-line PCX model. 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. 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 Onyx PCX reflects the ease of use, reliability and ruggedness customers have come to expect from Pickering Laboratories.

아미노산 분석을 위한 프로그래밍 운도 구배 (Programmable Temperature Gradient: Amino Acids Analysis)

The Onyx PCX provides an unique opportunity to combine the eluant gradient capabilities of modern HPLC instruments with programmable column temperature gradients. As might be expected, this capability helps reduce Amino Acids Analysis run times. Even more significant is the ability to resolve coelutions. Consider such metabolic markers as Alloisoleucine (MSUD) and Argininosuccinic acid (ASA); under standard isothermal conditions these amino acids coelute with Cystathionine and Isoleucine respectively, but both are resolved using a targeted temperature gradient program. The ability to accomplish this derives from the multiple retention mechanisms of the gel-type resins employed in ion-exchange, enabling all the amino acids to appear in the same chromatogram. The exact position of each amino acid is influenced by an array of mechanisms including partitioning, adsorption, charge exclusion, etc. So even though two amino acids might coelute, their proximity is incidental. And since retention processes are affected differently by changes in pH, salt concentration and temperature, all these parameters have significant influence on selectivity.




Onyx PCX 운용 소프트웨어 (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. The computer physically connects to the Onyx PCX unit through a USB cable. After an easy installation and configuration, the software runs in a window or as an icon on the computer desktop. The main software display matches the instrument’s digital LCD display, where all PCX functions of temperature, flow rate and system status are displayed in real time.


This allows for monitoring and control of the PCX and HPLC from one computer. Methods are managed within the PCX Control Software and can be created, edited and saved to create a library for all application parameters. A sequence table is used to schedule multiple runs of the same or different methods in a series. At the end of the sequence a full system flush can be programmed. System and pump performance can be evaluated in the maintenance menu, using a pump pressure test and system pressure test. An instrument log file continually records system status and error messages for later reference and can be sent to Pickering Labs Support for remote diagnostics.




시린지 펌프 & 밸브 (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.





The reactor is designed for quick heating and easy switching between applications. The heating and control electronics are in the base unit of the reactor while the coil volumes are inserted with a ‘quick-change’ cartridge on the front fluidics panel. The temperature range holds within 1 °C resolution from 5 °C above ambient room temperature to 130 °C maximum setpoint.




컬럼 히터(Column Heater)

The column heater utilizes recirculating airflow technology to provide quick and uniform column heating. Fast column cooling is assisted by the introduction of a fresh air flow into the chamber. The temperature range holds within 1 °C resolution from 5 °C above ambient room temperature to 75 °C maximum setpoint. The temperatures can be programmed for a gradient with as many steps as required for fine-tuning an analysis.
