| 摘要 |
The invention relates to optical instrument making and can be used in gas-analytical devices for measurement of emission of heat-electric power plants and of industrial enterprises in which gases with periodical structure in UV spectral area are present. A spectrometer includes a source of radiation, condenser system, cuvette for gas mixture being analyzed, polychromator with inlet and outlet slots, with possibility of spectrum scanning, receiver of radiation, resonance amplifier and diaphragm. The technical result of the invention is in decrease of error of measurement due to shift of the spectrum of analyzed gas in the outlet plane of the spectrometer. |
