Reliable separation and efficient group-type quantitation of total petroleum hydrocarbons (TPH)

In this article published in 'The Column' (Sept 2024) , the analysis of TPH in environmental media is simplified using flow-modulated GCxGC–FID with quantitation based on pre-defined compound groupings. This approach overcomes the drawbacks of conventional solvent fractionation approaches, by eliminating the need for sample fractionation and automating data processing workflows.
