PURPOSE:To perform the high sensitivity detection and quantitative analysis of gaseous S in a non-destructive manner without disturbing a system, by utilizing a spectral line with a predetermined wavelength by absorption of gaseous S. CONSTITUTION:Spectral lines with wavelengths of 263nm, 265.5nm, 268nm, 270.5nm, 273nm, 276nm, 279nm and 282nm are simultaneously incident to gaseous S in a cell 1 from a light emitting source 3. The absorption of incident spectral lines by gaseous S is measured by a light receiving part 4 and the detection and quantitative analysis of S are performed from the peak height of each light intensity. |
