This Technical Specification (CEN/TS) was approved by CEN on 26 June 2023 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

Introduction
[7]
This document was developed in response to biomethane specifications such as EN 16723 (all parts) .
In other regions, other specifications can apply for biomethane.
In the process of biogas upgrading into biomethane, alkanolamines are used for removing of sulphur-
containing components and carbon dioxide. Due to this reason, trace level of these components can
be present in biomethane. This method is suited for the detection of these components as well as the
determination of their concentration. To inject biomethane into natural gas grids and to use it as an
automotive fuel, it needs to meet specifications. For amines the maximum limit value in biomethane is
3 [7]
set as 10 mg/m is set in EN 16723 (all parts) . Other specifications can state other thresholds.

TECHNICAL SPECIFICATION ISO/TS 2610:2022(E)
Analysis of natural gas — Biomethane — Determination of
amines content
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.
