ALS determines persistent organic pollutants (POPs) in emission and ambient air by isotopic dilution method using high resolution gas chromatography combined with high resolution mass spectrometry (HRGC-HRMS). Our client can order analysis of dioxins (PCDD/F), polychlorinated biphenyls (indicator PCB and coplanar PCBs) or polycyclic aromatic hydrocarbons (PAH). These groups can be determined separately or combined, in regard of the requirements on sampling and the very high selectivity of their determination.
