*Direct replacement: this category indicates an alternative column which will likely give a similar selectivity.
You asked for optimized performance for pesticides by GC/ECD detectors, without time-consuming method development. We’ve delivered a direct replacement*! ZB-CLPesticides-1 and -2 provide guaranteed drop-in performance compared to your current Rtx-CLPesticides column set, without the hassle.
“ I was able to install the ZB-CLPesticides-1 and ZB-CLPesticides-2 columns as a direct replacement for the Restek Rtx-CLPesticides and Rtx-CLPesticides2 columns that I currently use. I made no changes to the method and saw very little difference between the two columns.“
