Abstract / scope
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.
