Abstract
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 %.
