Alcance
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.
