A Post Column Derivatization (PCD) System is a powerful analytical tool designed to chemically modify analytes after chromatographic separation but before detection. By introducing a selective reagent into the post-column flow path, the system enhances the analyte’s detectability, especially for UV/VIS, fluorescence, and electrochemical detectors. PCD is essential in amino acid analysis, phosphorus/sulfur detection, metal ion quantification, and environmental testing. The PCD system integrates seamlessly with HPLC and ion chromatography (IC) systems and ensures precise reagent delivery, efficient mixing, and stable reaction temperatures, optimizing both reaction kinetics and analytical sensitivity.
