SUMMARY OF WHITE PAPER
Polycyclic aromatic hydrocarbons (PAHs) are a class of structurally related hydrocarbons consisting of two or more fused aromatic/cyclic rings. PAHs are carcinogenic, they persist in the environment and bioaccumulate with potential adverse effects on aquatic life and humans: hence, they are classed as priority hazardous substances under the Water Framework Directive. The monitoring of PAHs in water is important to check that exposure does not present a risk to organisms, including humans.
The aim of this White Paper is to optimize and produce a robust and repeatable method for the analysis of PAHs in water, using GC-MS and hydrogen carrier gas produced in situ by a hydrogen generator. Then, the aim is to determine if hydrogen is suitable as the carrier gas for the separation and detection of PAHs in water.
The method developed using generated hydrogen as the carrier gas for the LLE-LVI-GC-MS determination of PAHs in water shows very good potential in speed and separating capacity. No adverse effects were observed concerning possible reaction of hydrogen carrier gas with analytes or the stationary phase of the GC column. The purity of the carrier gas as provided by the VICI DBS NM Plus hydrogen generator was fully satisfying.
