    10 APPENDIX APPENDIX 10.1 Measurement Principle The ultraviolet absorption method is based on ozone's characteristic of absorbing ultraviolet rays of specific wavelength. In this analysis method, the sample gas which has passed through the filter is divided into two flow paths. The sample gas in one path is introduced to the deozonizer, where its ozone is eliminated, and then sent to the cell as “reference gas.”...
