In order to achieve high sensitivity and selectivity of the analyte in high performance liquid chromatography (HPLC), labeling is performed with a derivatizing reagent appropriate for the detection method.
Methods include the pre-column method, in which the analytes are labeled in advance, and the post-column method, in which the analytes are labeled with derivatizing reagents after HPLC separation.
