Analysis of natural gas - Biomethane - Determination of terpenes' content by micro gas chromatography (ISO 2614:2023)
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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
Terpenes can occur naturally in biogas and remain as trace components after treatment in the
biomethane produced. Terpenes are odoriferous compounds that have the potential to mask the smell
of the odorant added to the biomethane before injection into the natural gas grid. For safety reasons it
is necessary to monitor these impurities.
This document describes a method to perform the analysis of five terpenes in biomethane. The method
includes both on-line and offline measurement techniques based on chromatography and can be of
interest to fuel specifications for biomethane.
This document contributes to the standardization of the determination of terpenes in biomethane. The
document relates to good housekeeping in supply of biomethane into the natural gas grid.
