Analysis of natural gas — Biomethane — Determination of terpenes’ content by micro gas chromatography

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.
