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.
