airmoTHM

A GC with a detector by conductivity for online survey of THM (Tri Halogen Methane) and/or Total Halogens (option)

This instrument uses an injection valve with a single trap, cooled at 14°C by Peltier effect
Sampling flow 20 /70 or 250 ml/min

• Capillary column (0.53) heated at 120°C.
  
• Miniaturization, sensitivity, mobility and flexibility are its main features. Everything from the sample port up to the data stOrage is integrated in a 19"-rack 4U.
  
• Isothermal temperature of the oven and pressure/flow control of the Helium carrier gas by the valve.
  
• Before final delivery the analyser is tested for two weeks by the Quality Control department.
  
• Conductivity detector. Halogen Specific with Propanol .The response is due to the formation of HF, HCL, HBr or HI. These acids are formed by hydrolysis of some halogenated hydrocarbons.
  
• Bi-directional RS-232 to transfer data temperature, pressure, status and results to the computer.
  
• The Vistachrom software enables the user to view and store data on a computer. It provides comfortable user-friendly utilities to recalculate, calibrate and export data and to configure the measurement.
  
• The software allows the calculation of retention time, area, mass or concentration profiles, in any international measuring unit.
  
• Calibration for validation : we use a permeation tube diluted by air for calibration.
