Select PAH Column

Agilent Select PAH GC Columns

Agilent J&W Select PAH columns are specifically engineered to deliver complete, high-resolution separation of polycyclic aromatic hydrocarbon (PAH) isomers—something traditional GC phases cannot achieve. By resolving structurally similar PAHs that commonly co-elute, Select PAH eliminates false positives, improves data confidence, and enables accurate quantification in environmental, food safety, petrochemical, and industrial applications.

Select PAH is the first capillary GC column capable of separating all critical PAH isomers in a single analysis, providing a streamlined alternative to multi-column or multi-method workflows. Its enhanced aromatic selectivity enables fast, reliable quantitation while reducing the need for confirmatory testing or secondary analyses.

This high-performance column delivers full separation of EPA-listed PAHs in under seven minutes and complete EU-regulated PAHs in under thirty minutes. It also resolves challenging isomer groups such as chrysene, triphenylene, and benzofluoranthene isomers (types b, j, and k), ensuring accurate identification without additional analytical steps.

As an authorized distributor of Agilent GC columns, Chrom Tech provides Select PAH as a powerful, time-saving solution for laboratories requiring exceptional resolution, rapid throughput, and uncompromising precision in PAH analysis.
Key Definitions â–¸
Select PAH
A high-selectivity GC column engineered to resolve all major PAH isomers in a single analysis. Select PAH eliminates co-elution issues and supports accurate, fast quantification of PAHs in environmental, food, and industrial samples.
PAH Isomers
Structurally similar polycyclic aromatic hydrocarbons that differ only in ring arrangement. These isomers frequently co-elute on general-purpose GC phases, requiring specialized aromatic selectivity for proper resolution and identification.
EPA and EU PAHs
Regulatory lists of priority polycyclic aromatic hydrocarbons established by the U.S. EPA and European Union. These PAHs are monitored due to their toxicity and environmental persistence. Select PAH provides complete separation of both EPA- and EU-regulated lists in significantly reduced run times.
Frequently Asked Questions â–¸
Why is the Select PAH column preferred for PAH isomer analysis?
Select PAH provides the enhanced aromatic selectivity needed to resolve structurally similar PAH isomers that typically co-elute on standard GC phases. This prevents false positives and ensures accurate identification and quantitation.
How fast can Select PAH separate EPA and EU-regulated PAHs?
Select PAH can fully separate EPA-listed PAHs in under seven minutes and EU-regulated PAHs in under thirty minutes, significantly reducing run time while maintaining high-resolution capability.
Does Select PAH resolve challenging isomer groups such as chrysene and benzofluoranthene?
Yes. Select PAH is specifically engineered to separate difficult PAH isomer groups including chrysene, triphenylene, and benzofluoranthenes (types b, j, and k), eliminating the need for additional confirmatory analyses.
