    摘要: A gas analyzer has a simple composition and can measure multi-components at a high accuracy. A plurality of measuring cells, including a case where the cells are different in length from each other, communicate sequentially with each other through a communication part to form a single gas path. A cut-on filter as an infrared penetration/reflection means for diffracting spectrally an infrared wavelength is provided on a light source side. A NO.sub.X measuring cell 3 having a cell length of about 60 mm and a CO.sub.2 measuring cell 7 having a cell length of about 1 mm which communicate through the communication part with each other, and a capacitor microphone (an infrared-ray detector for NO.sub.X) and a pyroelectric detector (an infrared-ray detector for CO.sub.2) are provided on the infrared penetration and reflection sides of the optical filter.

    摘要: A gas analysis apparatus includes: a first reflector that reflects measurement light from a light emitting unit disposed outside a gas flue wall and transmitted through a sample gas. A light receiving unit outside the gas flue wall receives measurement light reflected by the first reflector. A second reflector outside the gas flue wall reflects measurement light toward the light receiving unit. A computing unit analyzes sample gas by allowing the measurement light to be reflected by the first reflector and performs correction or calibration of the gas analysis apparatus using known substances within an associated containing unit along the light path between the light emitting unit and the second reflector by allowing measurement light to be reflected by the second reflector. A switching unit outside the gas flue wall selectively removes or inserts the second reflector from the light path during component concentration analysis and correction or calibration, respectively.

    摘要: A probe for gas analysis is provided in a pipe through which sample gas flows. The probe includes a tubular member and one or more sample gas inflow portions. The tubular member is disposed to cross a flow of the sample gas, and includes a measurement field to which the sample gas is introduced. The one or more sample gas inflow portions are provided in the tubular member. The sample gas flows around, and flows into the measurement field through the one or more sample gas inflow portions.

    摘要: An air-driven shutter device is used in an optical analyzer. The optical analyzer includes a measurement field to which a sample is supplied, a light-emitting unit measurement field for emitting measuring light to the sample, a light-receptive unit for receiving the measuring light that has passed through the sample, and a purge air supplying unit for supplying purge air. The air-driven shutter device includes a shutter and a shutter opening and closing mechanism. The shutter is disposed between the light-emitting unit and/or the light-receptive unit and the measurement field. The shutter opening and closing mechanism keeps the shutter open with pressure of the gas supplied from the purge air supplying unit, and closes the shutter when the pressure of the gas supplied from the purge air supplying unit becomes lower than a predetermined level.
