Those enclosed by dotted lines are ponents in shielded thermostat.Depending on permanent electric dipole moment, CO2, SO2 and other polar molecules have vibrational and rotational structure, and can generate absorption upon coupling with long infrared radiation by incident characteristic wave. LambertBeer Law reflects principle of the absorption. I=I0exp(-aPL) I0incident light intensityIemergent light intensitya absorption coefficientPpartial pressure of the gasLlength of analysis bathGiven that CO2 and SO2 have strong absorption band at and , respectively, by measuring light intensity change after absorption, the instrument can analyze percentages of CO2 and SO2, based on which C and S content of measured sample can be established.Analysis room is prised of infrared source, reflecting mirror, modulation reticle, absorption cell, optical filter and detector. After infrared source rises to 800℃ upon electric heating, infrared radiation is generated. Optical signal is modulated to 80Hz alternating radiation signal by modulator, for incidence to absorption cell. After absorption by CO2 and SO2 in absorption cell, energy of optical radiations other than the wavelengths above is filtered by narrow band pass filter, followed by incidence of the light to detector, so that light intensities respectively corresponding to concentrations of CO2 and SO2 are detected. Afterwards, they get to be electric signal upon photoelectric conversion, followed by amplification and output of analog quantity signal. Analog quantity signal is converted to C and S percentage upon integral inversion after A/D (analog/digital) conversion and normalization.Analysis flow: for analysis, sample is first weighed on electric balance, followed by result input to microputer (or keyboard input), then incorporated w
