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: An ultraviolet light source is provided on one end of a cell into which a sample gas is introduced. A beam splitter for dividing beams which have been transmitted through the cell into two optical paths is provided on the other end of the cell. A first detector is provided in one optical path, and a second detector is provided in the other optical path. A gas filter filled with a component to be measured is positioned between the detectors and beam splitter so that a concentration of the component to be measured may be obtained on the basis of a difference between the output of the first detector and the product of the output of the second detector and an appointed constant. Influences resulting from components coexisting in the sample gas are reduced. Alternatively, an infrared light source may be provided on one end of a sample cell. A gas filter filled with a gas the same as the gas to be measured is provided at the other end of the sample cell. A reference filter filled with a non-absorbing gas is positioned parallel to the gas filter. A beam splitter and a detector are sequentially disposed downstream from the gas filter, and a mirror is disposed downstream from the reference filter. The mirror is positioned such that beams which passed through the reference filter may be directed to the beam splitter and, subsequently, the detector.

摘要: A method and apparatus for analyzing fluid by a multi-fluid modulation mode is characterized by subjecting a plurality of sample fluids (which may be different or a single sample fluid divided into a plurality of systems) to a fluid modulation by reference fluids at various frequencies, respectively. An analytical portion provided with only one sensor is simultaneously and continuously supplied with the respective sample fluids. An output signal from the sensor in the analytical portion is divided into signal components of the respective modulation frequencies for the respective sample fluids to rectify and level, whereby obtaining analyzed values about the respective sample fluids is achieved.
