1 Scope
This document specifies a micro gas chromatography method for the on-line or offline
determination of the content of five terpenes in biomethane, namely:
-
— alpha-pinene,
-
— beta-pinene,
-
— para-cymene,
-
— limonene,
-
— 3-carene.
The method is specifically developed for these five compounds. Information about the
compounds is given in Annex A.
The method is applicable to the determination of individual amount fractions of the
five terpenes from 1 µmol/mol up to and including 10 µmol/mol. With minor modifications it can
also be used for terpene amount fractions above 10 µmol/mol.
