Agilent DB-Dioxin GC Columns

Agilent J&W DB-Dioxin GC columns are purpose-built for the highly selective, trace-level analysis of polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)—two of the most toxic and tightly regulated classes of semivolatile organic pollutants. These columns deliver the precision, inertness, and resolution required for global dioxin and furan monitoring programs, ensuring accurate identification of individual congeners even in complex environmental, food, and industrial samples.

The DB-Dioxin phase is specifically engineered to resolve critical toxic isomers, including 2,3,7,8-TCDD and 2,3,7,8-TCDF, from all other positional isomers in a single chromatographic run. This exceptional selectivity eliminates co-elution challenges and enables confident quantitation needed for compliance with international regulatory frameworks.

To achieve optimal carrier gas velocity and maximize resolution for high-boiling PCDD/PCDF congeners, DB-Dioxin columns require operation with a 100-psi regulator. This ensures stable flow control, improved separation efficiency, and consistent performance when working with these highly chlorinated, low-volatility compounds.

As an authorized distributor of Agilent GC columns, Chrom Tech provides DB-Dioxin as a specialized solution for laboratories performing rigorous dioxin and furan testing where accuracy, sensitivity, and regulatory confidence are paramount.
Key Definitions â–¸
DB-Dioxin
A highly selective GC column engineered for the analysis of polychlorinated dibenzodioxins (PCDDs) and dibenzofurans (PCDFs). DB-Dioxin provides superior resolution of toxic congeners and extremely low bleed for trace-level analysis.
PCDDs and PCDFs
Polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are persistent organic pollutants formed during combustion and industrial processes. Due to their toxicity, they are strictly regulated and require highly selective chromatographic methods for accurate quantitation.
2,3,7,8-TCDD and 2,3,7,8-TCDF
Two of the most toxic and environmentally significant dioxin and furan congeners. DB-Dioxin columns are specifically designed to resolve these compounds from all other positional isomers in a single chromatographic run.
100-psi Regulator
A high-pressure regulator required to achieve the optimum carrier gas velocity and flow stability for DB-Dioxin columns. This ensures maximum resolution and consistent performance when analyzing high-boiling, low-volatility PCDD/PCDF congeners.
Frequently Asked Questions â–¸
Why is DB-Dioxin preferred for PCDD/PCDF analysis?
DB-Dioxin is engineered with highly specialized selectivity to resolve toxic congeners—particularly 2,3,7,8-TCDD and 2,3,7,8-TCDF—from all other positional isomers in one chromatographic run. This prevents co-elution and ensures precise quantitation for regulatory compliance.
Why is a 100-psi regulator required for DB-Dioxin columns?
High-pressure operation is necessary to achieve the optimal carrier gas velocity needed for separating high-boiling, low-volatility dioxins and furans. A 100-psi regulator provides the stable flow and efficiency required for maximum resolution and consistent performance.
Are DB-Dioxin columns suitable for international regulatory workflows?
Yes. DB-Dioxin columns are widely used in global monitoring programs for food safety, environmental testing, and industrial compliance. Their unmatched selectivity and low bleed meet the strict requirements for trace-level PCDD/PCDF detection worldwide.
