From proof to practice − Sampling and analysis for simplified quantification of siloxanes in biogas Agarwal, Ayush Torrent Fàbrega, Laura Indlekofer, Julian Madi, Hossein Culleton, Lucy P. Biollaz, Serge M.A. Ludwig, Christian Energia de la biomassa Biomass energy Siloxanes in biogas pose significant challenges to energy systems, leading to operational inefficiencies and increased maintenance costs. This study advances the liquid quench sampling system (LQ) for accurate quantification of siloxanes using gas chromatography hyphenated with inductively coupled plasma mass spectrometry (GC-ICP-MS). The LQ demonstrated a capture efficiency exceeding 94 % over a broad concentration range, with sample stability tests indicating < 10 % analyte loss over four weeks. A Round Robin Test with nine independent laboratories validated the method's reliability. Calibration with liquid standards is demonstrated, eliminating complications associated with gaseous standards. On-site sampling with centralized analysis makes the method feasible for facilities lacking advanced instrumentation. By accurately quantifying siloxanes, this approach supports optimization of gas cleaning systems to extend equipment life. This LQ-GC-ICP-MS method enables practical sampling and simplified quantification for effective siloxane monitoring to enhance biogas utilization 7 2025-12-05T14:57:33Z 2025-12-05T14:57:33Z 2025-12-05T14:57:33Z 2025-08-01 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed http://hdl.handle.net/10256/27841 info:eu-repo/semantics/altIdentifier/doi/10.1016/j.biortech.2025.132463 info:eu-repo/semantics/altIdentifier/issn/0960-8524 info:eu-repo/semantics/altIdentifier/eissn/1873-2976 info:eu-repo/semantics/altIdentifier/eissn/1873-2976 Reconeixement 4.0 Internacional http://creativecommons.org/licenses/by/4.0 info:eu-repo/semantics/openAccess Elsevier Bioresource Technology, 2025, vol. 429, art.núm.132463 Articles publicats (D-Q) Agarwal, Ayush Torrent Fàbrega, Laura Indlekofer, Julian Madi, Hossein Culleton, Lucy P.
