Omfang

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
