“…Flow analysis has also been used for both precolumn and postcolumn derivatization in liquid and ion chromatography [25,701. For example, the trace metals Co, Ni, Cu, Zn, Cd, and Pb were determined by ion chromatography followed by postcolumn reaction with 4-(2-pyridlazo)resorcinol with the absorbance measured at 500nm [71].…”

A reversed-phase HPLC coupled on-line to a radical scavenging detection system and MS/MS was developed in order to combine separation, activity determination and structural identification of anti-oxidants in complex mixtures in one run. The sample was separated by HPLC and the eluate split into two flows. The major portion was fed into an electrospray ionisation MS/MS system, while the minor part was mixed with a free radical, 2,2'-diphenyl-1-picrylhydrazyl (DPPH), and the reaction determined spectrophotometrically. The negative peaks, which indicated the presence of anti-oxidant activity, were monitored by measuring the decrease in absorbance at 517 nm. The developed method was successfully applied to the identification of anti-oxidant compounds in a fraction, obtained by solid-phase extraction, of an extract of a Thai medicinal plant, Butea superba Roxb. The anti-oxidant compounds were separated and identified as procyanidin B2, (-)-epicatechin and procyanidin B5.
