Analyse von Erdgas - Biomethan - Bestimmung von flüchtigen organischen Verbindungen durch thermische Desorptionsgaschromatographie mit Flammenionisations- und/oder Massenspektrometriedetektoren (ISO 2620:2024); Deutsche Fassung EN ISO 2620:2024
Overview
Depending on the production method, biogas usually contains volatile organic compounds (VOCs) such as terpenes, siloxanes, hydrocarbons, sulfur containing compounds, oxygenated hydrocarbons, halogenated hydrocarbons, ketones, alcohols, and esters. VOCs can also be found in the biomethane even after upgrading. This document describes a method for sampling and analysis of volatile organic compounds (VOCs), including siloxanes, terpenes, organic sulfur compounds, in natural gas and biomethane matrices, using thermal desorption gas chromatography with flame ionization and/or mass spectrometry detectors (TD-GC-FID/MS). The responsible national standardization committee is Working Committee NA 032-03-08 AA "Biogas" ("Biogas") at DIN Standards Committee Gas Technology (NAGas).
