- Application-specific columns for organochlorine pesticides and herbicides; exceed performance criteria for US EPA methods 8081, 608, CLP.
- Low bleed — ideal for GC/ECD or GC/MS analyses.
- Baseline separations in less than 25 minutes.
- Stable to 340°C.
Improved resolution and faster analyses, compared to 1701 or phenyl phases, make these the pesticide columns of choice. Rtx®-CLPesticides columns are specially designed to overcome the coelutions and analyte breakdown typically encountered in chlorinated pesticide analyses for EPA Methods 8081, 608, and CLP. By achieving baseline resolution of the 20 target analytes, more accurate qualitative data can be obtained, providing reliable identification without GC/MS.
Column bleed, measured by ECD, is extremely low at temperatures greater than 300°C, which is critical for baking-out the column to remove high-boiling compounds commonly found in pesticide/PCB extracts. An analysis time of fewer than 25 minutes improves throughput compared to other stationary phases. Faster analysis times also can be achieved by using the analysis program used with Stx™-CLPesticides/Stx™-CLPesticides2 columns.
