Restek Rtx-CLPesticides GC Columns

Restek Rtx-CLPesticides GC columns are engineered specifically for the analysis of organochlorine and organophosphorus pesticides, as well as herbicides, semivolatiles, and other regulated contaminants monitored under U.S. EPA Contract Laboratory Program (CLP) protocols. Their selectivity, inertness, and low bleed performance make them an industry standard for laboratories running EPA methods 8081, 8082, 8270, 525, and related global pesticide workflows.

The phase chemistry is optimized to cleanly separate complex mixtures of chlorinated pesticides such as DDT and metabolites, aldrin, dieldrin, endrin, chlordane, toxaphene, and PCBs. Rtx-CLPesticides delivers exceptional resolution of these heavily regulated contaminants while maintaining robust peak shapes and stable retention times—even for challenging thermally labile compounds.

Low column bleed ensures high sensitivity and clean baselines for GC-MS, while strong inertness supports GC-ECD workflows that demand precise quantitation and minimal system contamination. The columns exhibit excellent lot-to-lot reproducibility, supporting validated and legally defensible analytical workflows for environmental, agricultural, industrial, and public health testing.

As an authorized Restek distributor, Chrom Tech supplies Rtx-CLPesticides columns in multiple dimensions tailored for high-throughput pesticide monitoring and CLP-compliant analysis of complex sample matrices.

Key Definitions
CLP Pesticides
A classification of pesticides designated under the EPA’s Contract Laboratory Program, including organochlorine and organophosphorus pesticides requiring rigorous analytical methods.
Organochlorine Pesticides (OCPs)
Chlorinated hydrocarbons such as DDT, aldrin, and endrin—highly persistent compounds that require specialized GC phases for accurate and reproducible analysis.
ECD Compatibility
The low bleed and strong inertness of Rtx-CLPesticides make it ideal for ECD workflows that require exceptionally low background and high sensitivity for halogenated analytes.
Pesticide Breakdown Prevention
Restek’s column deactivation ensures thermally labile pesticides are not degraded during analysis, improving quantitation and reducing false negatives.
CLP-Compliant Selectivity
Stationary phase tuning that satisfies EPA CLP method requirements for separating and quantifying regulated pesticide mixtures across complex environmental matrices.
Frequently Asked Questions
Which EPA methods are Rtx-CLPesticides columns designed for?
These columns are optimized for EPA methods 8081, 8082, 8270, 525, and related CLP workflows targeting organochlorine pesticides, organophosphorus pesticides, and PCBs.
What makes Rtx-CLPesticides suitable for ECD detection?
The columns exhibit extremely low bleed and strong inertness, preventing halogenated pesticides from degrading and ensuring high sensitivity in ECD workflows.
Can the column handle complex pesticide mixtures like toxaphene?
Yes. Rtx-CLPesticides delivers strong resolution of toxaphene congeners and other multi-component pesticide mixtures commonly encountered in environmental samples.
Are these columns appropriate for GC-MS workflows?
Absolutely. Their low bleed performance supports high-quality mass spectral data, making them suitable for both GC-MS and GC-ECD pesticide testing.
