VOCs and volatile HAPs analyzer

Automatic Gas Analyzer for Volatile PAH compounds and VOCs monitoring

The auto GC-MS 866 uses a valve with a sampling trap.
It also features a metallic capillary column.
Its main characteristics are :

  • Miniaturization, sensitivity, mobility and flexibility

Everything from the sample port up to the data storage is integrated in a 19″ cabinet

  • Sampling with pre-concentration on absorbent tube.
  • Gas chromatograph with metallic column and programmable temperature gradient
  • Flow control of the carrier gas
  • FID and MS detectors

The Vistachrom software enables the user to visualize and store data on a PC. Furthermore, it provides comfortable utilities to recalculate, calibrate and export data and to set-up measurement.
The software allows the calculation of retention time, area, mas or concentration profiles. It manages all the items of the solution (multiplexer, Gas generators, Calibrator and more).
