Total petroleum hydrocarbons (TPH) represent a broad range of compounds derived from crude oil that pose potential environmental and human health risks when present in water. This application note describes the development and validation of a GC‑FID method for the determination of TPH in water using hydrogen as an alternative carrier gas. The method demonstrates excellent precision and specificity across a wide carbon range, while offering a practical response to ongoing helium supply constraints and supporting more sustainable laboratory operation
