Study on time -divided double optical paths ultraviolet fluorescence For concentration measuring of sulfur dioxide

摘要：

The research on the detection of sulfur dioxide concentration in flue-gas is a hot topic all the time. Based on the analysis of the measuring principles for the sulfur dioxide concentration using ultraviolet fluorescence method, one new measuring method using time-divided double optical paths is proposed. This method overcomes the problems of cross sensitivity and background noise in single path measurement, because it takes advantage of the fluorescence signals produced by the alternation of two light filters.
