Siloxane Monitoring System (Ei2300)

Precise on-site measurement of siloxanes in biogas, landfill and digester gas

The Siloxane Continuous Monitoring System is an independent and fully automated measurement system which has been developed to precisely quantify the concentration of linear siloxanes (L2, L3, L4, and L5), as well as the cyclic siloxanes (D3, D4, D5, and D6) in biogas. The instrument separates compounds in two independent stages, combining the selectivity of a Gas Chromatograph with the extraordinary sensitivity (low ppbv) of an Ion Mobility Spectrometer (IMS).
