摘要： PURPOSE:To measure hypochlorous acid alone in a sample water accurately by bringing the sample water containing the hypochlorous acid into contact with a carrier gas and then, by measuring the carrier gas with a semiconductor gas sensor. CONSTITUTION:Ambient air is sucked into a device with a pump 8. The air is dehumidified and purified with a filter 1 and one part is turned to a dry gas passing through a weighing meter 2 while the other part thereof is turned to a carrier gas passing through a flowmeter 3. When the carrier gas passes through a porous tube 5 immersed in a sample water within an extraction tank 4, isolated chlorine in the sample water passes through a fine pore of a tube 5 to diffuse into the carrier gas. In this apparatus, steam is mixed with the dry gas coming via the flowmeter 2 in the course of a piping to a measuring chamber 6 from the tube 5 so that it is not condensed. Thus, the carrier gas mixed with the dry gas is introduced to a measuring chamber 6 to measure a concentration of isolated chlorine with a semiconductor type gas sensor.

摘要： PURPOSE:To make stable and rapid measurement with good reproducibility and high sensitivity by bringing a soln. mixed with a sample liquid of trihalomethane into contact with a carrier soln. mixed with nicotinic acid amide and NaOH via a microporous membrane. CONSTITUTION:The carrier soln. mixed 5A with the nicotinic acid amide and NaOH is sent to the the inner side of the tube of a separator 2. On the other hand, the 2nd soln. mixed 5B with the sample liquid contg. the trihalomethane and a sodium sulfite soln. or hydrazine sulfate is sent to the outer side of a separator 2 but these two solns. do not mix as the tube consisting of the microporous membrane is made of 'Teflon(R)' and has water repellency. However, the trihalomethane in the 2nd soln. has high volatility and, therefore, diffuses in the form of gas into the micropores. This gas penetrates into the carrier soln. and forms a fluorescent condensate by reacting with the nicotinic acid amide in the presence of the NaOH. The carrier soln. is then cooled 6 to about 10 to 30 deg.C to prevent the degradation in sensitivity by the temp. extinction of the fluorescence. After bubbles are removed, the fluorescent condensate is fluorescently detected and determined in a detecting section 8.

摘要： PURPOSE:To make it possible to wash out effectively a stain sticking to an optical window of an immersion type optical cell. CONSTITUTION:A measuring part 1 formed by providing an optical window 2 for light application in one inner wall surface of a V-shaped groove opened at an angle of 90 deg. or below and an optical window 3 in the other inner wall surface, and an ultrasonic washing device having a vibrating surface on planes being opposite to the two inner wall surfaces of the V-shaped groove of this measuring part 1 and intersecting two planes containing the two inner wall surfaces of the V-shaped groove at equal angles, are provided in an immersion type optical cell. A plane wave generated from an ultrasonic vibrator is reflected on the two inner wall surfaces of the V-shaped groove of the measuring part and makes it possible to wash the surface of each optical window effectively. By generating a stationary wave by setting properly the angle of opening of the V-shaped groove, an oscillation frequency and the distance between the vibrating surface of the ultrasonic vibrator and the apex of the V-shaped groove and by providing the optical windows in the part of the antinode of the stationary wave, besides, a stronger washing effect can be displayed.

摘要： PURPOSE:To detect the abnormality of underground piping by exciting in terms of sound wave pipings buried in a burying body by a sound wave source installed in a branch pipe, and at the same time, irradiating microwave on the surface of the burying body near the place where the piping is buried. CONSTITUTION:A water leakage position detecting device 11 consists of an ultrasonic sound source installed mainly in the branch pipe 3 of a water pipe 1 and excites in terms of ultrasonic wave the water pipe 1 and water in the water pipe 1, a synchronizing signal detector 12, a microwave device 13 and a recorder 10. The ultrasonic wave sound source consists of a vibrator 6 and a vibrator driving device 7. The device 13 is provided movable near the ground surface, and irradiates microwave on the ground surface of the place where the water pipe 1 is buried, and at the same time, detects the reflected wave of the microwave modulated by feeble ultrasonic vibration of the ground surface propagated from the water pipe 1 through the ground 2. Thus, the presence of abnormality of the state of burying can be judged accurately.
