Abstract:

A new technique, high resolution quartz capillary column GC/MS/ESR combined with the silanization approach of free radical adduct was successfully used in the analysis and determination of 6 types of PBN spin adducts. Satisfactory mass spectra of spin adducts were obtained. The results show that it is an efficient method for separating and identifying mixed free radicals.

Key words: Spin trapping, GC/MS, Silanization, Free radical, ESR
