Innovative, Reliable, Smart


PyxisGC BTEX is the first and unique gaschromatograph “carrier gas free” for remote BTEX monitoring in ambient air. PyxisGC BTEX is manufactured by Pollution Analytical Equipment in compliance with EN14662-3:2015.

PyxisGC BTEX can measure those compounds thanks to the MEMS (Micro Electro-Mechanical Systems) pre-concentrator, GC separation column, based on a proprietary silicon micromachined chip and the miniaturized Photoionization detector (PID) that quantifies the peaks.

PyxisGC BTEX is equipped with a Cloud software to monitor and manage the acquired data: it is easily accessed via browser on your phone, tablet or PC. The Pollution Guardian Cloud software stores up and archives analysis data automatically, it allows the real time data and the historical data viewing (with creation of charts, tables, graphs and other statistical analyses).





PyxisGC BTEX Applications:

  • “Smart city” air quality monitoring
  • Fence line monitoring
