Unique Rtx®-CLPesticides Column Set Provides Optimal Results for Organochlorine Pesticides GC-Micro-ECD Analysis Using Any Carrier Gas
5 Nov 2014Over the past few years, the increasing costs and uncertain availability of helium have prompted many labs to explore alternate carrier gas options. This application note compares the performance of Rtx®-CLPesticides and Rtx®-CLPesticides2 columns to a competitor’s CLP column set using helium, hydrogen, and nitrogen carrier gases for a frequently used dual-column GC-ECD method. These column sets differ in selectivity, and since proprietary Rtx®-CLPesticides and Rtx®-CLPesticides2 columns were developed specifically for organochlorine pesticides analysis by GC-ECD, their unique column selectivities provide optimal resolution and fast analysis times whether operated using helium, hydrogen, or nitrogen carrier gases.
