1 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.
