Comparison of Retention on Various Stationary Phases and Thermodynamic Parameters of Retention on RTX-200MS GC Column for Isobutylesters of Perfluorinated Carboxylic Acids
Abstract
Perfluorinated organic acids (C6-C12) were analyzed by GC-ECD after their conversion to corresponding isobutyl esters by the reaction with isobutyl chloroformate. The retention of PFCA isobutyl esters on different stationary phases was measured and compared.
