Preparation of a C18 Stationary Phase Immobilized by Gamma Radiation for use in High Performance Liquid Chromatography

A liquid stationary phase, poly(methyloctadecylsiloxane), was immobilized on a silica support, in the proportion 50:50 m/m, by gamma radiation doses of 20 to 90 kGy, with the purpose of obtaining a highly stable chromatographic stationary phase. This stationary phase exhibited higher efficiency and...

Description
Summary:A liquid stationary phase, poly(methyloctadecylsiloxane), was immobilized on a silica support, in the proportion 50:50 m/m, by gamma radiation doses of 20 to 90 kGy, with the purpose of obtaining a highly stable chromatographic stationary phase. This stationary phase exhibited higher efficiency and shorter analysis times than similar columns prepared with commercial C 18 packings.
