Seven EPA Methods on One Column Pair using a µ-ECD

Seven EPA Methods on One Column Pair using a µ-ECD

Analyze Pesticides, PCBs, Herbicides and More on a Single Rtx®-CLPesticides Column Set

Get improved resolution, faster analyses, and less downtime by using Rtx®-CLPesticides and Rtx®-CLPesticides2 columns for multiple GC/ECD methods. Instead of changing columns between methods, you can save time by analyzing chlorinated pesticides, PCBs, herbicides, and other halogenated compounds on a single column set using an Agilent µ-ECD. Rtx®-CLPesticides and Rtx®-CLPesticides2 columns have a unique selectivity and outperform other column sets offered specifically for multiple GC/ECD methods.
