Optimization of infrared techniques for environmental monitoring

A new method far IR monitoring of the content of total dust, coal dust, and smoke gas in atmospheric industrial emissions is proposed. By this method, the intensities of the forward-scattered and transmitted infrared (IR) radiation in the smoke layer are measured. The dust or gas concentration is determined from the ratio of LR signals measured at different wavelengths. The method proposed permits simultaneous quantitative determination of a range of compounds with severalfold improved accuracy of measurement.
