Agilent PAH GC Columns

Agilent PAH GC columns are purpose-designed for the accurate, high-resolution analysis of polycyclic aromatic hydrocarbons (PAHs) across environmental, food safety, petrochemical, and industrial testing workflows. These columns provide the selectivity, sensitivity, and ruggedness needed to resolve structurally similar PAH isomers that often co-elute on standard phases. Their enhanced inertness and optimized retention characteristics support reliable quantitation of both low-level and high-boiling PAHs, even in complex matrices.

Chrom Tech, as an authorized distributor of Agilent chromatography supplies, offers two specialized PAH-focused GC column families. The Select PAH column provides sharp peak shapes, strong aromatic selectivity, and excellent resolution for multiring hydrocarbons—ideal for regulatory and routine PAH profiling. The DB-EUPAH column delivers extended selectivity tailored to stringent European Union (EU) and international PAH monitoring programs, offering robust separation power for isomeric compounds and improved stability for heavy, high-boiling PAHs.

Together, Agilent Select PAH and DB-EUPAH GC columns offer laboratories a complete, application-optimized solution for achieving accurate identification, dependable retention, and reproducible quantitation of PAHs in demanding analytical environments.
Key Definitions â–¸
Select PAH
A GC column engineered for high-resolution separation of polycyclic aromatic hydrocarbons. Select PAH delivers strong aromatic selectivity, sharp peak shapes, and enhanced resolution for multi-ring and structurally similar PAH compounds.
DB-EUPAH
A specialized Agilent GC column designed to meet stringent European Union (EU) and international regulatory requirements for PAH monitoring. DB-EUPAH provides enhanced selectivity for isomeric PAHs and improved performance for high-boiling, heavy, or contaminated matrices.
Polycyclic Aromatic Hydrocarbons (PAHs)
A class of multi-ring aromatic compounds formed through combustion, industrial processes, and natural degradation of organic materials. PAHs are environmentally persistent and regulated due to their toxicity, requiring highly selective chromatographic phases for accurate separation and quantitation.
Frequently Asked Questions â–¸
Why are specialized GC columns required for PAH analysis?
PAHs consist of structurally similar multi-ring aromatic compounds that often co-elute on standard GC phases. PAH-specific columns such as Select PAH and DB-EUPAH provide enhanced aromatic selectivity and optimized retention, enabling reliable resolution and accurate quantitation of individual PAHs.
What is the difference between Select PAH and DB-EUPAH columns?
Select PAH is designed for high-resolution separation of a wide range of PAHs, offering excellent peak symmetry and aromatic selectivity. DB-EUPAH provides enhanced selectivity for PAH isomers and is optimized to meet stringent European Union (EU) and international regulatory monitoring requirements.
Are these PAH columns suitable for environmental compliance testing?
Yes. Both Select PAH and DB-EUPAH are widely used for regulatory compliance testing in environmental laboratories. Their strong selectivity, inertness, and retention consistency support accurate monitoring of priority PAH pollutants in soil, water, air, and industrial samples.
