[A gas chromatographic method for detecting nitrites in the blood and stomach contents]. / Gazokhromatograficheskii metod obnaruzheniia nitritov v krovi i soderzhimom zheludka.

Ethyl nitrite method is proposed as the tentative test for nitrites in studies of the blood and gastric contents. The sensitivity of the method in "pure" solutions is 17 micrograms/sample. The method is specific and its sensitivity is not inferior to routine chemical analyses of biological materials for nitrites.

[The isolation and determination of different narcotic and drug substances after the acid hydrolysis of biological material. (1)]. / Izolirovanie i opredelenie razlichnykh narkoticheskikh i lekarstvennykh veshchestv posle kislotnogo gidroliza biologicheskogo materiala (soobshchenie 1).

A modified method for isolation of toxicologically significant substances after acid hydrolysis of biological material is proposed. Drugs and narcotics of different groups were identified, which are not disintegrated after acid hydrolysis of biological material and are isolated in high amounts.
