Aliphatic/Aromatic Petroleum Hydrocarbons in Waters by GCxGC-FID
aliphatic banding: >C5–C6, >C6–C8, >C8–C10, >C10–C12, >C12–C16, >C16–C21, >C21– C35, >C35– C44
aromatic banding: >C5–C7, >C7–C8, >C8–C10, >C10–C12, >C12–C16, >C16– C21, >C21– C35, >C35– C44
Methodology – Liquid/liquid solvent extraction of a water sample into pentane followed by determination of total petroleum hydrocarbons by two dimensional gas chromatography using flame ionisation detection (GCxGC-FID).
