Agilent DB-608 GC Columns

Agilent J&W DB-608 GC columns are precision-engineered for the targeted analysis of chlorinated pesticides, herbicides, and polychlorinated biphenyls (PCBs). Designed to meet the strict demands of regulatory monitoring, these columns offer the selectivity and inertness required for accurate quantitation of halogenated compounds commonly evaluated under U.S. EPA methods. DB-608 is widely used for EPA 608, 508, and 8080 workflows, where it delivers consistent peak shape, reliable recovery, and minimal pesticide breakdown.

The column’s bonded and crosslinked construction provides excellent thermal and chemical stability, enabling routine solvent rinsing to extend column lifetime and maintain stable retention behavior. With an operating temperature range of 40 to 280/300 Â°C, DB-608 supports both routine and high-temperature GC methods, offering the robustness needed for complex environmental and agricultural matrices.

As an authorized distributor of Agilent GC columns, Chrom Tech offers DB-608 as a trusted solution for high-confidence pesticide and PCB analysis in laboratories performing regulatory screening, compliance testing, and trace-level environmental monitoring.
Key Definitions â–¸
DB-608
A highly selective GC column engineered for the analysis of chlorinated pesticides, herbicides, and PCBs. DB-608 is optimized for EPA regulatory workflows and delivers minimal analyte breakdown with strong peak integrity.
EPA Methods 608, 508, and 8080
U.S. EPA regulatory methods for analyzing chlorinated pesticides, herbicides, and PCBs in water, wastewater, and environmental samples. DB-608 is widely used due to its superior selectivity and low analyte breakdown.
Bonded and Crosslinked Phase
A chemically reinforced stationary phase structure that enhances thermal and solvent stability. This allows DB-608 columns to be solvent rinsed and maintain long-term retention consistency during high-temperature or contaminated-matrix analyses.
Frequently Asked Questions â–¸
Why is DB-608 commonly used for EPA pesticide methods?
DB-608 provides the selectivity, inertness, and low breakdown necessary for chlorinated pesticide and PCB analysis under EPA Methods 608, 508, and 8080. Its phase chemistry enables accurate separation and reliable quantitation of halogenated analytes.
Can DB-608 withstand high-temperature GC methods?
Yes. With an operating temperature range of 40 to 280/300 Â°C, DB-608 supports high-temperature workflows while maintaining stability, low bleed, and consistent retention performance.
What benefits does the bonded and crosslinked phase provide?
The bonded and crosslinked phase increases thermal and solvent stability, allowing routine solvent rinsing and extended operational lifetime. This enhances reproducibility and ensures DB-608 performs reliably in contaminated or complex environmental matrices.
