This application note demonstrates the performance of the Select PAH GC column for multi-residue analysis
Polycyclic aromatic hydrocarbons (PAHs) are often analyzed alongside polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs). Multi-residue analysis is challenging due to the wide range of compounds and potential co-elution of isomers, which can lead to false positives. This document addresses these challenges by demonstrating the capabilities of a specific column for separating complex mixtures.
| Technique | GC/MS |
|---|---|
| Column Part Number | CP7462 |
| Column Dimensions | 30 m x 0.25 mm, df=0.15 um |
| Analysis Time | 25 minutes |
| Injection Volume | 1 pL |
The method screens and quantifies polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs).
It has unique capabilities for the separation of isomers, resolving false positives and inaccurate results caused by co-elution.
The analysis includes p,p'-DDT, o,p'-DDT, cis-heptachlor epoxide, trans-heptachlor epoxide, and others listed in Table 1.
