Monolithic capillary columns for analysis of permanent gases and light hydrocarbons
Monolithic capillary columns based on divinylbenzene and ethylene glycol bis(acrylate) polymers were applied toward the analysis of permanent gases and light C(1)-C(2) hydrocarbons by gas chromatography. It was shown that columns on the basis of the ethylene glycol bis(acrylate) polymer demonstrate better separating ability and make it possible to separate all components of the standard mixture at room temperature except the N(2)/O(2) pair. The columns on the basis of divinylbenzene exhibit lower selectivity but make it possible to perform rapid analysis of the standard mixture with an analysis time less than 2 min.
