Siloxane Analyzer (GC-IMS-SILOX)

Excellent sensitivity for every siloxane species, without matrix interferences

The GC-IMS-SILOX is a stand-alone device developed for user-friendly and reliable on-site siloxanes measurements in biogas, landfill, sewage gas, and digestors. The device has a straightforward single-click menu and can alternatively be run as an online monitoring system, automatically testing the gas in user-defined intervals. Results are stored on its flash memory and shown on the 6.4" touchscreen, or the 'Total Si' value is transferred via 4–20mA or MODBUS (TCP). 

Besides power, the GC-IMS SILOX only needs N2 or synthetic air as drift and carrier gas for operation. Its user-friendly menu allows for a non-specialist to operate the instrument. Alternatively, it can be used as an online/continuous monitor at set intervals running 24/7.

  • User-friendly, one-click menu allows for operation of the system without a specialist

  • Low detection limits (µg/m3) with 'total silica' (SiO2) and 'total silicon' (Si) results

  • High accuracy

  • Standard ranges available: Low: Single siloxanes (L2–L5, D3–D5): 0.03–2mg/m3 and ‘Total Si‘: 0.1–5.0mg/m3 High: Single siloxanes (L2–L5, D3–D5): 0.1–5mg/m3* and ‘Total Si’: 0.4–12mg/m3

  • Adjustable alarm settings

  • Compact design

  • Now supported by a published ASTM Standard, D8455

Available Options

µTD GC-IMS Thermo-Desorber

  • Automated analyte absorption and thermal desorption unit (µTD)

  • The micro TD preconcentrates the sample before injecting into BreathSpec to gain more compounds from the breath (see final image)

  • On-site sub-ppb detection of volatiles

  • Spatial combination of sampling onto adsorption tubes and thermal desorption with subsequent analysis on-site

  • Improved sensitivity due to analyte enrichment on adsorption trap
