| Abstract: | The non-dispersive infrared gas analysis technique and its application in sulfur dioxide measurement are presented. The absorbance acquisition and concentration retrieval in non-dispersion sulfur dioxide analysis are analyzed. By taking the third-order polynomial as a fitting model, the calibration curve is obtained with the nonlinear least-square. The measurement accuracy of the system is analyzed and the measurement error less than 2 % is derived. The result shows that the non-dispersive infrared technique can measure the sulfur dioxide accurately and it can also be used in the analysis of other gases. |
