Issue date: 2024 05 15

Analysis of natural gas - Silicon content of biomethane - Part 2: Determination of siloxane content by gas chromatography with ion mobility spectrometry (ISO 2613-2:2023)

This document describes a gas chromatography – ion mobility spectroscopy (GC-IMS) method for the determination of the concentration of siloxanes in biomethane. The method is applicable to the following siloxanes: - hexamethyldisiloxane (L2); - octamethyltrisiloxane (L3); - decamethyltetrasiloxane (L4); - dodecamethylpentasiloxane (L5); - hexamethylcyclotrisiloxane (D3); - octamethylcyclotetrasiloxane (D4); - decamethylcyclopentasiloxane (D5); - dodecamethylcyclohexasiloxane (D6). This document describes suitable calibration and measurement strategies to quantify siloxanes in (bio) methane around and above the 0,3 mg m^(-3) (14 µmol mol^(-1)) level and applies to analyses within absolute pressure ranges of 1 bar – 2 bar, temperatures of 0 °C – 40 °C and relative humidity < 90 %.

Frequently Asked Questions about ÖNORM EN ISO 2613-2

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.
