Analysis of natural gas -- Biomethane determination of halogenated compounds -- Part 1: Part 1: HCl and HF content by ion chromatography prEN ISO 2611-1

Scope

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.
