The construction of a microdetector, based on the principle of polarography, for liquid chromatography and its application are described. The characteristics of the flow cells with a horizontal dropping mercury electrode (HDME), a vertical dropping mercury electrode (DME), and a mercury plated platinum electrode (Hg–Pt) are compared with each other. The flow cell has been applied to the analysis of a mixture of nitropyridine derivatives, such as 2-amino-3-nitropyridine (A3N), 2-amino-5-nitropyridine (A5N), 2-hydroxy-3-nitropyridine (O3N), 2-hydroxy-5-nitropyridine (O5N), and 2-nitroaminopyridine (NA), by means of a reversed-phase partition column or an ion-exchange column. In quantitative analysis, a standard deviation of better than 3% can be obtained.
