摘要：

A flow-through electrochemical detector with a carbon fibre electrode was fabricated. A chromatographic method for the determination of vitamin B6 using this detector is described, and the results are compared with those obtained by detection with a thin-layer glassy carbon electrode or spectrophotometry. The detection limit of vitamin B6 is 2.5 ng for pyridoxine, 1 ng for pyridoxal and 1 ng for pyridoxamine. The technique was applied to the determination of vitamin B6 in tablets. © 1990.
