[The determination of benzodiazepines in biological objects on the Milichrome microcolumn liquid chromatograph].
1,4-benzodiazepines and benzophenols, the products of their hydrolytic cleavage, were measured by high-pressure liquid chromatography in expert material (stomach, liver, intestine, kidney samples). Milichrome microcolumn liquid chromatograph, designs 1 and 2, was employed, with a chromatography column packed with Separon C18 (5 microns) sorbent. A mixture of (NH4)2HPO4 (0.05 M) and acetonitryl in volume ratio 65:35 was used as the mobile phase in native compound analysis and that in volume ratio 45:55 for benzophenols and medazepam separation. The external standard method was used for quantitative estimation.
