Total HydroCarbons analysis with chromaTHC
CH4 and Non Methane Total Hydro Carbon (NMTHC) Monitoring and analysis of Methane and Non-Methane Hydrocarbons by flame ionisation detection (ppm level analysis)
The CHROMATHC is an automated isothermal industrial gas chromatograph dedicated to the analysis of volatile organic compounds in air (indoor, outdoor, combustion), industrial hygiene, pure gas like N2/CO2/O2.
- As a fully automatic instrument, the CHROMATHC allows un-attended operation after commissioning 24/24.
- The injection is made via a loop and valve installed in an isothermal oven at a standard 80°C.
- The separation between CH4 and (C2H6 for UHC) and NMTHC is achieved using a column with back flush.
Unlike other similar analysers, there is no interference from oxygen.
To eliminate issues with flame fluctuaction, a valve regulates carrier gas (hydrogen or Nitrogen or air).
The retention time drift is less than 0,3 %.
- The instrument has a flame ionization detector (FID) heated at 150°C with auto ignition.
