Abstract: A method of selective nitrogen determination was worked out for azoxy compounds, triazene and pentaza-l,4-diene derivatives; it is based on the destruction of the compounds in wet way with gas chromatographic deter­ mination of liberated elemental nitrogen by frontal technique. Decom­position of compounds proceeds in the apparatus placed in front of the chromatographic unit of the CHN-1 analyzer. The worked out method makes the determination of nitrogen possible in separate functional groups giving reliable and exact results and extending application possibilities of the apparatus.
