本文件规定了生物甲烷中链烷醇胺浓度的测定。测量方法包括具有火焰离子化和/或质谱检测器的热解吸气相色谱(TD-GC-MS/FID)。所描述的方法专门用于分析五种胺化合物，即: —？单乙醇胺(MEA)； —？二甘醇胺(DGA)； —？二乙醇胺(DEA)； —？N-甲基二乙醇胺(MDEA)； —？哌嗪（PZ）。 有关化合物的信息见附件？A.

This document specifies the determination of the concentration of alkanolamines in biomethane. The measurement method involves thermal desorption gas chromatography with flame ionization and/or mass spectrometry detectors (TD-GC-MS/FID). The described method is specifically developed for the analysis of five amine compounds, namely: —？monoethanolamine (MEA); —？diglycolamine (DGA); —？diethanolamine (DEA); —？N-methyldiethanolamine (MDEA); —？piperazine (PZ). Information about the compounds is given in Annex？A.
