Analysis of natural gas - Biomethane - Determination of halogenated compounds - Part 1: HCl and HF content by ion chromatography (ISO/FDIS 2611-1:2024)
This document specifies a method for the determination of the concentration hydrochloric acid and hydrofluoric acid in biomethane, after absorption on an alkali-impregnated quartz fiber filter or in a sorbent trap, by ion chromatography (IC) with conductimetric detection. The method is applicable to biomethane in levels: - for HCl: 0,07 mg/m3 to 34,3 mg/m3; - for HF: 0,07 mg/m3 to 17,5 mg/m3.
