Precise on-site Quantification of Siloxanes in Biogas, Landfill and Digester Gas
The GC-IMS-SILOX is a stand-alone device that has been developed for user-friendly and reliable one-site measurements of siloxanes in biogas, landfill or sewage gas.
The device has a straight-forward single-click menu and can alternatively be run as online monitoring system testing the gas automatically in user defined intervals. Results of siloxanes, silica (SiO2) same as silicon (‘Total Si’) are stored on its flash memory and shown on the 6.4" touchscreen or the ‘Total Si’ value is transferρed via 4–20mA or MODBUS (TCP). To run the system it only takes power and nitrogen (cylinder or N2 -generator).
Advantages of G.A.S.’ GC-IMS-SILOX for siloxane analysis:
- On-site measurements with “one-click” menu
- On-line/continuous monitoring at set intervals
- Very low detection limits (µg/m3) with 'total silica' (SiO2) and 'total silicon' (Si) results transferred via4-20mA or MODBUS (TCP)
- High reproducibility and accuracy
- Very low running and maintenance costs
Flexible sampling is assured by an integrated pump and a six-port valve to either test from gas sample-bags or as preferred directly from the gas pipe via a by-pass. Condensation water can be trapped by the use of an optional (GENIE-) filter.
Its menu allows that an on-site test can securely be carried out by non-specialists. Alternatively it can be used as a 24/7 based on-line monitoring tool to test for individual siloxanes at their relevant concentration levels to take immediate on-site decisions.
