Agilent J&W DB-EUPAH GC columns provide the optimal performance for the analysis of European Commission regulated priority PAHs, including the separation of the most critical isomers such as Benzo(b,k,j)fluoranthenes. Exceptional thermal stability with low column bleed at elevated temperatures and consistent column inertness performance ensure accurate analysis of heavier dibenzopyrene isomers. The DB-EUPAH columns deliver fast and reliable results while meeting the demanding regulatory requirements.



Two-Part QC Testing For Superior Quality and Optimal Performance



1. Isothermal analysis to ensure reproducibility of the stationary phase selectivity and retention and provide assessment of column efficiency and phase coating efficiency.

Test Probe	Column Functional Test
p-Toluidine	Acidity
Tetradecane	Hydrocarbon marker
4-Chlorophenol	Basicity
1-Undecanol	Silanol and column selectivity
2-Methylnaphthalene	Column selectivity
Hexadecane	Hydrocarbon marker
Methyl Dodecanoate	Retention
Acenaphthylene	Column efficiency

2. Application-specific temperature program to ensure the separation of the regulated priority PAHs with nice peak shapes as well as the resolution of critical isomer pairs

Test Probe	Column Functional Test
Phenanthrene Anthracene	• Column efficiency for resolution of critical aromatic isomers • US EPA regulated priority PAHs
Pyrene	• US EPA regulated priority PAH
Chrysene	• EU regulated priority PAH
Benzo-[b]-fluoranthene	• EU regulated priority PAHs • Column efficiency for resolution of critical aromatic isomers
Benzo-[k]-fluoranthene
Benzo-[j]-fluoranthene

This new two-part testing procedure is built on the already tightest industry QC specifications for bleed, inertness, sensitivity, and efficiency. It goes a long way in assuring a successful analysis for the challenging analytes, providing you the most confidence in the analysis results.
