Agilent Pesticides GC Columns

Agilent Pesticides GC columns are engineered to deliver accurate, robust, and reproducible separations for a wide range of pesticide residues in food, environmental, agricultural, and industrial matrices. These columns are designed to handle heavy sample loads, complex extractables, and thermally demanding methods while maintaining excellent peak shape, low bleed, and consistent retention times.

As an authorized distributor of Agilent chromatography supplies, Chrom Tech offers four specialized GC column families tailored for pesticide analysis. The VF-5 Pesticides column provides optimized inertness and selectivity specifically for multi-residue workflows, supporting high-throughput screening and confirmation. The VF-1701 and DB-1701P columns offer enhanced mid-polarity selectivity ideal for organochlorine, organophosphate, and carbamate pesticides, helping resolve structurally similar analytes that are difficult to separate on nonpolar phases. For regulatory monitoring requiring chlorinated pesticide analysis, DB-608 delivers outstanding resolution and reduced breakdown of sensitive compounds, making it a preferred choice for EPA-driven applications.

Together, these Agilent GC columns form a comprehensive, application-focused portfolio that supports laboratories performing routine screening, trace-level quantitation, or regulatory pesticide compliance testing. Their high thermal stability, rugged deactivation chemistry, and proven long-term performance make them indispensable tools for reliable pesticide residue analysis.
Key Definitions â–¸
VF-5 Pesticides
A low-polarity GC column optimized for multi-residue pesticide analysis. VF-5 Pesticides delivers high inertness, excellent peak shape, and the selectivity needed for broad-spectrum screening across complex matrices such as food and environmental samples.
VF-1701
A mid-polarity GC column containing 14% cyanopropyl phenyl and 86% dimethylpolysiloxane. VF-1701 provides enhanced separation for organochlorine, organophosphate, and carbamate pesticides, particularly when structural similarity causes co-elution on nonpolar phases.
DB-1701P
An Agilent mid-polarity column designed specifically for pesticide residue testing, featuring low bleed, strong thermal stability, and optimized selectivity for EPA and international regulatory methods involving chlorinated and semi-volatile pesticides.
DB-608
A highly selective GC column engineered for chlorinated pesticides, herbicides, and other halogenated compounds. DB-608 reduces thermal breakdown of sensitive analytes and provides the resolution necessary for high-confidence confirmation under EPA regulatory methods.
Frequently Asked Questions â–¸
Which Agilent GC column is best for multi-residue pesticide analysis?
The VF-5 Pesticides column is specifically optimized for broad-spectrum multi-residue workflows. Its high inertness and low bleed make it ideal for food and environmental laboratories performing screening and confirmation of diverse pesticide classes.
What is the difference between VF-1701 and DB-1701P?
Both are mid-polarity phases designed for improved separation of structurally similar pesticides. VF-1701 is a versatile option for organochlorine, organophosphate, and carbamate analysis, while DB-1701P is engineered specifically for pesticide residue methods with lower bleed and enhanced thermal stability suited for regulatory testing.
When should I choose DB-608 for pesticide analysis?
DB-608 is the preferred choice for chlorinated pesticide methods and EPA-driven regulatory workflows. Its selectivity and reduced thermal breakdown help maintain integrity of halogenated analytes that may degrade on standard phases.
