Study on radiation degradation of hydroxylamine derivatives. Pt.1: Gas chromatographic analysis of gas hydrocarbons produced by radiation degradation of hydroxylamine derivatives

This paper reports the gas chromatographic analysis of gas hydrocarbons possibly produced by the radiation degradation of N,N-dimethylhydroxylamine and N,N-diethylhydroxylamine, porous layer open tubular column coated with aluminum oxide and flame-ionization detector are used. The best gas chromatographic analysis condition is as follow: column temperature: two steps programmed temperature: first step: initial temperature: 40 degree C, initial isothermal period: 9 min, programmed heating rate: 6 degree C/min, final temperature: 88 degree C, final isothermal period: 1 min; second step: initial temperature: 88 degree C, initial isothermal period: 1 min, programmed heating rate: 3 degree C/min, final temperature: 200 degree C, final isothermal period: 1 min; detector temperature: 250 degree C
