Run 7 EPA Methods On One Column Set
Zebron ZB-CLPesticides-1 and -2 allow you to run multiple methods without changing columns for faster, easier pesticide analysis. Save time and gain flexibility – run multiple pesticide classes on one instrument, on one column pair.

  • Resolve multiple pesticide classes with enhanced, fine-tuned selectivity
  • Meet dual-column requirements for 7 EPA methods by GC-ECD
    • 8081: Chlorinated Pesticides
    • 8082: Polychlorinated Biphenyls (PCBs)
    • 8151: Chlorinated Herbicides
    • 504: EDB, DBCP, and TCP
    • 505: Organohalide Pesticides
    • 508: Chlorinated Pesticides, Herbicides, and Organohalides
    • 552: Haloacetic Acids (HAAs) and Dalapo

*Direct replacement: this category indicates an alternative column which will likely give a similar selectivity.

Direct Replacement for Restek Rtx-CLPesticides Phases

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.

Drop-In Results: Real Customer Data, Real Performance

“ 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.“
