Analyse von Erdgas - Biomethan-Bestimmung von halogenierten Verbindungen - Teil 1: HCl- und HF-Anteil durch Ionenchromatographie (ISO 2611-1:2024); Deutsche Fassung EN ISO 2611-1:2024
Overview
This document specifies a method for the determination of the concentration of hydrochloric acid (HCl) and hydrofluoric acid (HF) in biomethane, after absorption on an alkali-impregnated quartz fibre filtre or in a sorbent trap, by ion chromatography (IC) with conductimetric detection. This method is also applicable to biogas and is intended to support conformity assessment of biomethane and biogas according to specifications, such as the EN 16723 series. The method is applicable to biomethane for concentration levels for HCl from 0,07 mg/m3 to 35 mg/m3 and for HF from 0,07 mg/m3 to 20 mg/m3. The responsible national standardization committee is Working Committee NA 032-03-08 AA "Biogas" ("Biogas") at DIN Standards Committee Gas Technology (NAGas).
