特點
• The injection is made via a loopａnd heated rotary valve.
• Trap for concentration of NMTHC in ppb application
• The separation between CH4 and NMTHC is achieved using a trap back flush with thermodesorption.
• No oxygen effect
Synergism occurs.
• 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 or 200 ° C.
其他：
The Vistachrom software enables the user to visualize and store data on a computer. Furthermore it provides comfortable utilities to recalculate, calibrate and export data and to set-up measurement. The airmoTREND software allows the calculation of retention time, area, mass or concentration profiles.
CH4 and Non Methane Total Hydro Carbon NMTHC A gas analyser for Hydrocarbon and VOC with flame ionization detection It is an automated isothermal industrial gas chromatographdedicated to the analysis of volatile organic compound in air (indoor, outdoor, combustion), industrial hygiene, pure gas like N2/CO2/O2.
As a fully automatic instrument, it allows un-attended operation after commissioning 24/24.
