Dieses Dokument beschreibt ein Gaschromatographie-Ionenbeweglichkeitsspektrometrie-(GC-IMS-) Verfahren zur Bestimmung der Konzentration von Siloxanen in Biomethan. Das Verfahren ist auf folgende Siloxane anwendbar:
— Hexamethyldisiloxan (L2)
— Octamethyltrisiloxan (L3)
— Decamethyltetrasiloxan (L4)
— Dodecamethylpentasiloxan (L5)
— Hexamethylcyclotrisiloxan (D3)
— Octamethylcyclotetrasiloxan (D4)
— Decamethylcyclopentasiloxan (D5)
— Dodecamethylcyclohexasiloxan (D6)
Dieses Dokument beschreibt geeignete Kalibrier- und Messstrategien zum Quantifizieren von Siloxanen in (Bio)Methan um ein und über einem Niveau von 0,3 mg m−3 (14 μmol mol−1) und gilt für eine Analyse innerhalb eines absoluten Druckbereiches von 1 bar bis 2 bar, bei Temperaturen von 0 °C bis 40 °C und bei einer relativen Feuchtigkeit von <90 %.

Analyse du gaz naturel - Teneur en silicium du biométhane - Partie 2: Détermination de la teneur en siloxane par chromatographie en phase gazeuse avec spectrométrie de mobilité ionique (ISO/FDIS 2613-2:2023)

Le présent document décrit une méthode de chromatographie en phase gazeuse ‒ spectroscopie de mobilité ionique (CG-SMI) pour la détermination de la concentration de siloxanes dans le biométhane. La méthode s'applique aux siloxanes suivants:
—     hexaméthyldisiloxane (L2);
—     octaméthyltrisiloxane (L3);
—     décaméthyltétrasiloxane (L4);
—     dodécaméthylpentasiloxane (L5);
—     hexaméthylcyclotrisiloxane (D3);
—     octaméthylcyclotétrasiloxane (D4);
—     octaméthylcyclotétrasiloxane (D5);
—     dodécaméthylcyclohexasiloxane (D6).
Le présent document décrit les stratégies d'étalonnage et de mesure appropriées pour la quantification des siloxanes dans le (bio)méthane aux environs et au-dessus du niveau de 0,3 mg m−3 (14 µmol mol−1) et s'applique aux analyses dans des plages de pression absolue de 1 bar à 2 bar, des températures de 0 °C à 40 °C et une humidité relative < 90 %.
