Abstract: Optical waveguide paths to observe a sample on a sample holder from a plurality of directions while guiding an image of light in each direction which is emitted out of the sample toward a direction of a two dimensional detector via a main imaging lens include an optical waveguide path which never receives the light directly from the sample. The optical waveguide path which never receives the light directly from the sample forms an image of the sample within a substantial focus range of the main imaging lens, and includes optical elements arranged such that a light beam after formation of the image proceeds toward a direction of the main imaging lens. Optical elements on at least one optical waveguide path are those for forming real images. Therefore, the main imaging lens images the sample and those real images in block on the two dimentional detector.

Abstract: PROBLEM TO BE SOLVED: To provide a fluorescence analyzer water capable of measuring the content of sulfur dioxide without interfering with nitrogen monoxide even if nitrogen monoxide is contained in the measured gas. SOLUTION: The light from an exciting light source 2 in a light source chamber 1 passes through the gas filter 4 of an exciting wavelength selection section 3, the light near the wavelengths 214 nm and 226 nm is selectively absorbed j the nitrogen monoxide gas sealed in a gas filter 4, and the light of the wavelength 250 nm or above is absorbed by an optical filter 5. The sulfur dioxide in the sample gas is excited by this light and emits fluorescence, however the nitrogen monoxide emits no fluorescence because the light of the wavelengths 214 nm and 226 nm for excitation is lacking, only the fluorescence by the sulfur dioxide reaches a detector 10 in a detection section 9 as the light of the wavelength 300-400 nm through the optical filter 8 of a fluorescence wavelength selection section 7, and the fluorescence intensity of the sulfur dioxide is measured.

Abstract: PURPOSE:To reduce an error at fluorescence detecting time, and prevent the degradation of S/N by reducing stray light received by a fluorescence detector by being reflected directly or inside of a fluorescent chamber among excitation light, by a shielding body. CONSTITUTION:In a fluorescence detecting process, first of all, sample gas is sealed in a fluorescent chamber 4 from a sample introducing part 5. Among white light nondirectionally emitted by a Xe lamp 1, only light having a wave length in an extremely narrow band of a half value width of about 6nm with 214nm particularly as its center is selected by a band-pass filter for exciting light, and is applied to the fluorescent chamber 4. SO2 in the fluorescent chamber 4 is excited by this light, and emits fluorescence in a wave length area of 230 to 400nm. Among this fluorescence, only a wave length of 300 to 400nm is transmitted by a band-pass filter for fluorescence, and is detected by a photomultiplier 8. Here, since a light shielding body 11 is arranged, among exciting light, stray light received by the photomultiplier 8 by being reflected directly or inside of the fluorescent chamber 4 is attenuated. Thereby, an error at fluorescence detecting time can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a measuring apparatus for suspended particulate matter, having high detection sensitivity and little adhesion of suspended particulate matter.
SOLUTION: The suspended particulate matter measuring apparatus is provided with a sample gas channel 51a for introducing a sample gas; a detection part 5 having a detector for collecting the suspended particulate matter in the sample gas introduced and detecting the concentration of the suspended particulate matter; and a flow quantity control part 3 and a suction pump 4 for drawing a prescribed quantity of flow of the sample gas in the sample gas channel 51a. A PTFE (polytetra-fluoroethylene) compound plated layer 51c, formed by making a fluorine-containing resin combined and eutectoid with electroless nickel plating is formed in the inner surface of the sample gas channel 51a. By the plating layer, electrical conductivity is obtained and the suspended particulate matter is prevented from adhering to the sample gas channel 51a.

Abstract: PROBLEM TO BE SOLVED: To attain high measuring sensitivity. SOLUTION: A β-ray is emitted from a β-ray source 8A to measure the β-ray transmitted through only a filter paper 1 by a β-ray detector 9A, prior to collection, in a position A, to be stored in a control/computing part 12 as an initial count value I0 . The filter paper 1 is fed thereafter by a pinch roller 3 to collect a suspended particulate substance in a collecting part 7. An initial count value I0 of a new portion in the filter paper 1 is measured concurrently in the position A at that time. After a collection time for the particulate substance passes, the pinch roller 3 is driven again to measure a β-ray transmission quantity in a position C. By this manner, the measurement of the initial count value I0 for the filer paper 1 only, the collection of the particulate substance, measurement of a count value I for a deposit layer of the filter paper 1 and the particulate substance are carried out concurrently in parallel, so as to calculate a concentration of the suspended particulate substance successively.

Abstract: PURPOSE: To provide the fluorescence measuring apparatus, which excludes the time instability of a pulse lighting light source and the effect of the offset of a circuit and can accurately measure the amount of the fluorescence. CONSTITUTION: Of the pulse light emitted from a xenon flash lamp 1, the optimum wavelength region for exciting SO2 is selectively transmitted through an optical filter 2 and applied into sample gas in a fluorescent chamber 3. Then, the fluorescence emitted from SO2 in the sample gas is cast into a photomultiplier 5 through an optical filter 4, which selects and passes only the wavelength region of the fluorescence. Meanwhile, the pulse light, which has passed through the fluorescent chamber 3 passes a light dispersing element 6 and enters a photodiode 7. A timing signal is supplied into an A/D converter circuits 10 and 11, respectively, after the specified time since the output of a preamplifier circuit 9 exceeds a threshold value level Vs. At this time, the outputs of the preamplifiers 8 and 9 are inputted into a CPU12, and the measured concentration value SO2 is operated.

Abstract: PURPOSE:To reduce noise as much as possible without obscuring the variation in the amount of an object itself. CONSTITUTION:A polynomial fitting method is employed (step S8, S9) when a value sigma /r, obtained by dividing the variance sigma of measurements taken during a predetermined section by the mean value (r) of the measurements, exceeds a predetermined threshold value otherwise a simple moving average method exhibiting higher noise reduction effect is employed (step S4, S7).
