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.
