1.1 This test method is for the determination of volatile sulfur-containing compounds and minor hydrocarbons in gaseous fuels including components with higher molar mass than that of propane in a high methane gas, by gas chromatography (GC) and atomic emission detection (AED). Hydrocarbons include individual aliphatic components from C₄ to C₆, aromatic components and groups of hydrocarbons classified according to carbon numbers up to C₁₂ at least, such as C₆-C₇, C₇-C₈, C₈-C₉ and C₉-C₁₀, etc. The detection range for sulfur and carbon containing compounds is approximately 20 to 100 000 picograms (pg). This is roughly equivalent to 0.04 to 200 mg/m³ sulfur or carbon based upon the analysis of a 0.25 mL sample.
