Abstract: PURPOSE: To accurately measure fluorescence by detecting the concentration of an object component contained in a sample, and changing the pulse lighting period of a pulse lighting light source according to its concentration. CONSTITUTION: A CPU 6 gives indication to a trigger generating circuit 7, and generates the light emitting timing signal of a xenon flash lamp 1. When the exciting light is irradiated from the lamp 1, SO2 in a sample chamber 2 is excited, and emits fluorescence. A photomultiplier 3 detects this, and data is taken in the CPU 6 through a preamplifier 4 and an A/D converter 5. The CPU 6 calculates the average value of the data with respective pulses by ordinary moving average operation, and performs operation on dispersion of the data on the basis of it. When a signal is changed when a signal condition is judged, that is, when a newly taken-in signal is beyond a range of dispersion, it is judged that a sudden change in a fluorecent quantity (the concentration) is caused, and indication is given to the circuit 7, and a pulse period is changed. The concentration is calculated, and this is repeated.

Abstract: PURPOSE:To make possible highly sensitive detection of even a very small amount of a sample by providing a reflection mechanism for reflecting light with a specified wavelength area alone on an internal wall surface of a light source chamber to increase the intensity of excitation light. CONSTITUTION:A sample gas is sealed into a fluorescence chamber 9 from a sample introduction part 14. White light emitted in a non-directional manner with a Xe lamp 1 has ultraviolet rays alone reflected in a light source chamber 2 and the most of light moves to a band pass filter 7 for excitation light. With the band pass filter 7 for excitation light. light with an extremely narrow band wavelength about 6nm in half value width especially centered on 214nm is selected and transmitted out of the light selected in wavelength within the light source chamber 2 to irradiate the fluorescence chamber 9. Thus, SO2 in the fluorescence chamber 9 is excited to emit fluorescence with a wavelength range of 230-400nm. Out of the fluorescence, that with the wavelength of 300-400nm alone is transmitted with a band pass filter 10 for fluorescence and detected with a photomultiplier tube 13.

Abstract: PURPOSE:To make it possible to measure only gas to be analyzed by providing an optical filter on the excited-light irradiating side and/or fluorescence emitting side of a fluorescence chamber, and cutting the wavelength region for exciting an interference component and/or the fluorescence wavelength region caused by the interference component. CONSTITUTION:Sample gas is sealed into a fluorescence chamber 3. For the white light emitted from the Xe lamp of a light source part 1, only the wavelength in the very narrow band is selected and transmitted through an optical filter 2, and the light is applied to the fluorescence chamber 3. Thus, the sample gas in the fluorescence chamber 3 is excited. The fluorescence in the specified wavelength region is emitted. Of the fluorescence, only the specified wavelength is transmitted with the optical filter 4, and the wavelength region for exciting an interference component and/or the wavelength region of the fluorescence from the interference component is cut. Therefore, only the component to be measured can be measured. The fluorescence of the transmitted wavelength is detected with a photomultiplier, and the concentration of the gas is measured.
