FIELD: measurement equipment.SUBSTANCE: method consists in measurement of coefficient of absorption of infrared radiation the analysed mix of gases containingCOorCO passed through single-pass or multipass to a ditch, thus measurement of coefficient of absorption of radiation is taken in the range of lengths of waves from 1.94 to 2.18 microns, or from 2.50 to 2.80 microns, or from 4.00 to 4.50 microns, or from 14.00 to 17.00 microns for moleculesCO, and in the range of lengths of waves from 2.30 to 2.50 microns or from 4.50 to 5.10 microns for moleculesCO. The selection of the named ranges, the spectral accuracy and ditche type is caused by presence of other main gas components, formed during processing of spent nuclear fuel, and also by the concentration of the moleculesCOorCO and the value of the common pressure in the ditch.EFFECT: higher accuracy.8 cl, 5 dwg |
