Analysis of organic compounds formed in electron avalanches in a proportional counter filled with Ar/C2H4 gas mixture

Some organic chemical compounds formed in electron avalanches have been analyzed by using a tandem gas chromatograph equipped with a cryogenic sample concentration unit. The characteristics of the analyzer are described. Fifteen stable compounds created in a proportional counter filled with Ar/C2H4 50/50 gas mixture were identified. Several compounds containing double or even triple bonds were found. Some potential reactions leading to production of the compounds are shown. Production rates of two compounds were observed to depend on the irradiation rate.
