Pinnacle PCX Derivatization Instrument

The Pinnacle PCX Delta 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 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. 

System Design Advancements Result in Optimized Analysis

  • The electronic syringe pump provides true pulse-free flow 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 flushing.
  • 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 flow 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. Inert flow path extends system life and reduces maintenance.
  • The PCX control software allows for precise control of the reagent delivery and conservation.
  • Works with any HPLC system.
  • RoHS compliant

Feature Highlights

The Chromatogram in Figure 1 demonstrates some of the clear advantages of the temperature gradient program. Compared 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 specific compound of interest.
