People are using increasing amounts of siloxanes which ultimately end up in landfills, then in landfill gas and biogas digesters. Their presence poses difficulties for industries to use the energy content of landfill gas and biogas because the combustion process oxidizes Si to SiO2 which in turn damages engine parts. Rapid, efficient, accurate methods are needed to quantify the presence of siloxanes. Selected ion flow tube mass spectrometry (SIFTMS), an emerging real-time technique, is used to monitor trace volatile compounds in air. Samples containing the trace volatile compounds are drawn into the flow tube and convected in a He stream. Chem. ionization reactions from mass-selected reagent ions with the volatile compounds occur. To quantify volatile compounds in the sample, the ion chem. of the reagent ion with each volatile must be known. Rate coefficients and product ion branching ratios were determined for dodecamethylpentasiloxane, decamethylcyclopentasiloxane, decamethyltetrasiloxane, octamethylcyclotetrasiloxane, triethylsilanol, tetramethylsilane, and hexamethyldisilazane. The ion/mol. reactions of these 7 Si-containing compounds were fast, occurring at or near the collision rate, allowing for low concentration detection. The very simple reaction chem. of proton transfer, electron transfer, and Me loss enables easy siloxane quantitation in landfill gas and biogas by SIFTMS. Copyright © 2013 John Wiley & Sons, Ltd.
