ÖNORM EN ISO 2612

Issue date: 2024 06 15

Analysis of natural gas - Biomethane - Determination of ammonia content by Tuneable Diode Laser Absorption Spectroscopy (ISO 2612:2023)

This document describes several test methods for measuring the ammonia amount fraction in natural gas and biomethane at the trace level (µmol mol^(-1)). The suitable handling and sampling of pressurised mixtures of ammonia in methane that are applied to several different ammonia measurement systems are described. The measurement systems are comprised of readily available commercial spectroscopic analysers that are specific to ammonia. These NH(3) analysers are considered as a black box in terms of their operation, which is dependent on the instructions of the manufacturer. The document describes suitable calibration and measurement strategies to quantify ammonia in (bio)methane around and above the 10 mg m^(-3) (14 µmol mol^(-1)) level and applies to analysis within absolute pressure ranges of 1 bar - 2 bar, temperatures of 0 °C - 40 °C and relative humidity <90 %. References are also made to additional standards that are applied either to natural gas analysis or air quality measurements. In this document the matrix gas is always methane or biomethane and the measurand is the amount fraction NH(3).

Frequently Asked Questions about ÖNORM EN ISO 2612

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
