Annotation of standard text ČSN EN ISO 2613-2 (385581):
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 %
