CO2、SO2气体分子在红外光波段，具有选择性吸收谱图功能 1. CO2 and SO2 gas molecules have the function of selective absorption spectrum in the infrared light band
CO2, SO2 and other polar molecules have electric dipole moments, so they have structures such as vibration and rotation.
Divided into split energy levels according to quantum mechanics, it can be coupled with incident characteristic wavelength infrared light to generate absorption.
Gas molecules have a selective absorption spectrum in the infrared light band. When infrared light of a specific wavelength passes through CO2 or SO2 gas, it can produce strong light absorption.
2.The detector converts light signals into electrical signals
When the detector operates in a linear region, a specific wavelength is selected and the length of the analysis cell (absorption cell) is determined.
The measured light intensity can be converted into the concentration of the measured gas in the mixed gas. This is the basic principle of the infrared absorption method for quantitative measurement of gas concentration.
The measuring wavelength selected by this instrument: CO2 is 4.26um, SO2 is 7.4um.
检测到的是与CO2、SO2浓度相对应的光强，经一定处理积分反演成为碳硫元素的百分含量 3. The light intensity corresponding to the concentration of CO2 and SO2 is detected, and the percentage content of carbon and sulfur elements is inverted after a certain processing integration.
The analysis room includes a miniature infrared light source, a reflector, a modulation motor, an absorption cell, a filter and a detector.
The miniature infrared light source is electrically heated to 800 ° C to generate infrared light. After being absorbed by the absorption cell by CO2 and SO2, it passes through a narrow-band filter to filter out the energy of other light radiation outside the above wavelength and enter the detector.
The light intensity detected by the detector corresponds to the concentration of CO2 and SO2, which is converted into electrical signals by the photoelectricity of the detector, and then normalized and calibrated by a microcomputer. The integral inversion becomes the percentage content of carbon and sulfur elements. A modulation motor is placed between the light source and the absorption cell to modulate the optical signal into a 64Hz alternating radiation signal. The center frequency of the detector output is 64Hz.
The electrical signal converted from the pyroelectric device is pre-amplified and post-amplified and then entered into a microcomputer through digital-to-analog conversion. In the microcomputer, it is converted into a value proportional to the content of CO2 and SO2 through linearization.
