One single analyzer for measurement of:NO, NO2, NOx, N2O, CO, CO2, SO2, HCl, HF, CH4, TOC and O2
Operating principle:An optical ray, emitted by the IR source, passes through the measurement chamber and is focused on an IR detector.
Each gas that is present on the path of the optical ray, absorbs the latter at defined wave-lengths that are specific to it.
An interference filter that defines a specific wavelength area is positioned on the optical path above the measurement chamber.
On the optical path are alternatively placed a cell filled with the gas to be measured (high concentration) and a cell filled with nitrogen, which does not absorb at any wavelength.
A cell filled with highly concentrated gas that needs to be measured and a cell filled with nitrogen, which does not absorb any wavelength, are positioned on the optical path alternately.
The highly concentrated gas, which is in the cell called the reference cell, absorbs all wave-lengths that are specific to it. Even if gas molecules are present in the measurement chamber and on the optical path, all wavelengths that should have been absorbed by them, have already been absorbed. Therefore, the energy received by the detector can be considered to be constant and can serve as an IR reference for this gas, in spite of its dependence on other phenomena (e.g. power of the infrared source, presence of particles…).
Some milliseconds later, the cell filled with nitrogen is positioned on the optical path. Absorption of the infrared energy is due to the gas in the measurement chamber, according to the Beer Lambert law.
Model MIR IS uses a 16-hole correlation wheel, on which are installed the interferential filters and gas cells, thus allowing simultaneous measurement of several gases.
