标准摘要
[中文适用范围]: 该文件规定了通过离子色谱法(IC)和电导检测法,测定吸附在碱性浸渍石英纤维滤膜或吸湿阱中的生物甲烷中盐酸(HCl)和氢氟酸(HF)浓度的方法。该方法适用于HCl浓度从0.07 mg/m3到35 mg/m3以及HF浓度从0.07 mg/m3到20 mg/m3的生物甲烷。除非另有说明,本文件中所有浓度均在标准参考条件下给出(参见ISO 13443)。其他条件也可以适用。该方法同样适用于沼气。该方法旨在支持根据如EN 16723系列等规范对生物甲烷和沼气的一致性评估。 [外文原描述]: 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. The method is applicable to biomethane for concentration levels for HCl from 0,07 mg/m 3 to 35 mg/m 3 and for HF from 0,07 mg/m 3 to 20 mg/m 3 . Unless stated otherwise, all concentrations in this document are given under standard reference conditions (see ISO 13443). Other conditions can be applied. This method is also applicable to biogas. This method is intended to support conformity assessment of biomethane and biogas according to specifications, such as the EN 16723 series.
