airmoVOC - Model C6-C20+ -Volatile and Semi Volatile Hydrocarbons Analyzers
A GC/FID instrument for Volatile and Semi Volatile Hydrocarbons measurement in ambient air. The airmoVOC C6C20+ is used to monitor VOCs up to the semi volatile hydrocarbons in industrial site, tropical forest and on site under decontamination. With detection limit as low as 1 ppt for Benzene or Naphthalene the system can measure gaseous PAHs in ambient air in continue up to Fluorene and linear alcanes up to N-Hexadecane when coupled to Mass Spectrometer.
The fully automatic system allows to detect such compounds thanks to internal sampling line and ultra-high sensitivity.
Specific Vistachrom Software is used to pilot the instrument as well as the peripherals (e.g. gas generators) which can be provided with the instrument.
