Determination of Oil & Grease; HEM (n-Hexane Extractables) & Total Petroleum Hydrocarbons (SGT-HEM) for Sludge & Solid Samples
Applicability: This procedure applies to the analysis of oil and grease for sludge, soil, and other solid materials amenable to chemical drying and solvent extraction with n-Hexane.
Summary: Oil & Grease (HEM) & Total Petroleum Hydrocarbons (SGT-HEM) include any material that may be recovered as a substance that is soluble in n-Hexane; including relatively non-volatile hydrocarbons, vegetable oils, animal fats, waxes, soaps, greases, and related materials.
