Siloxane analysis using Q-Tof (Targeted analysis)

The UNSW Odour Lab operates a variety of GC-MS systems that can be set-up for the targeted analysis of key analytes for different applications.  

An example of which is the identification and quantification of siloxane type compounds, which are common problematic contaminants in biogas.  

Applications 

Based on industry requirements, a method was developed in-house for the accurate quantification of siloxanes in biogas produced from wastewater treatment plant anaerobic digesters and landfills.   

Siloxanes are found in many consumer and laboratory products, and volatile components can become concentrated in biogas streams. When these compounds are combusted to recover energy, it can lead to increased maintenance due to silica deposition in equipment.
