Summary
This document describes a gas chromatography method? ion mobility spectroscopy (CG-SMI) for the determination of the concentration of siloxanes in biomethane. The method applies to the following siloxanes: — hexamethyldisiloxane (L2); — octamethyltrisiloxane (L3); — decamethyltetrasiloxane (L4); — dodecamethylpentasiloxane (L5); — hexamethylcyclotrisiloxane (D3); — octamethylcyclotetrasiloxane (D4); — octamethylcyclotetrasiloxane (D5); — dodecamethylcyclohexasiloxane (D6). This document describes appropriate calibration and measurement strategies for the quantification of siloxanes in (bio)methane around and above the level of 0.3 mg m-3 (14 µmol mol-1) and applies to analyzes in absolute pressure ranges of 1 bar to 2 bar, temperatures of 0 °C to 40 °C and relative humidity < 90%.
