Abstract
Overview
EN ISO 6975:2005 (identical to ) defines an . It specifies how to separate and quantify gases and hydrocarbon fractions using gas chromatography with thermal conductivity (TCD) and flame ionization detectors (FID). The standard supports detailed composition analysis (C1 to C5, C6+ fractions, inert gases and selected aromatics) required for calorific value, density, vapor‑phase equilibrium and feedstock evaluation.
