Analysis of natural gas - Biomethane - Determination of terpenes' content by micro gas chromatography (ISO/FDIS 2614:2023)

This document defines a Micro Gas Chromatography method for the fast and quantitative analysis of five types of terpenes in biomethane, allowing their monitoring online or offline, and covering the range from 1 ppm mol to 10 ppm mol.

Analyse von Erdgas - Analyse von Biomethan - Bestimmung des Terpengehaltes durch Mikrogaschromatographie (ISO/FDIS 2614:2023)

Dieses Dokument legt ein Mikrogaschromatographie-Verfahren für die direkte oder indirekte Bestimmung des Gehalts von fünf Terpenen in Biomethan fest, und zwar:
— alpha-Pinen,
— beta-Pinen,
— para-Cymen,
— Limonen,
— 3-Caren.
Das Verfahren wurde speziell für diese fünf Verbindungen entwickelt. Informationen zu den Verbindungen sind in Anhang A angeführt.
Das Verfahren ist anwendbar auf die Bestimmung der einzelnen Stoffmengenanteile der fünf Terpene von 1 μmol/mol bis einschließlich 10 μmol/mol. Mit geringen Modifikationen kann es auch für Terpen-Stoffmengenanteile über 10 μmol/mol angewendet werden.

Analyse du gaz naturel - Biométhane - Détermination de la teneur en terpènes par micro-chromatographie en phase gazeuse (ISO/FDIS 2614:2023)

Le présent document spécifie une méthode de détermination en ligne ou hors ligne de la teneur de cinq terpènes dans le biométhane par micro-chromatographie en phase gazeuse, à savoir:
—     l’alpha-pinène;
—     le bêta-pinène;
—     le para-cymène;
—     le limonène;
—     le 3-carène.
La méthode est spécifiquement développée pour ces cinq composés. Des informations sur les composés figurent à l’Annexe A.
La méthode est applicable pour la détermination de fractions molaires individuelles des cinq terpènes allant de 1 µmol/mol jusqu’à 10 µmol/mol inclus. En apportant des modifications mineures, cette méthode peut également être utilisée pour des fractions molaires de terpènes supérieures à 10 µmol/mol.
