摘要： A gas sampling bag is capable of blowing out the gas uniformly into the bag main body, and filling the bag main body with gas in a securely mixed state. A gas sampling bag that is connected to a constant volume sampling passage, contains a pipe, on which a plurality of gas inlet/outlet holes are formed, in a bag main body, and allows the gas to flow into/out of the bag main body through the gas inlet/outlet holes. The opening of the plurality of gas inlet/outlet holes is formed in such a manner that the size is minimized while the pressure loss is suppressed so as not to increase as far as possible.

摘要： A forming method for a calibration curve in an infrared gas analyzer. The forming method minimizes the systematic error that occurs in the infrared gas analyzer improves measuring precision. The forming method modifies a method in which gases having different concentrations are supplied to an infrared gas analyzer. The gas analyzer has the outputs corresponding to the gas concentrations, and samples the gas concentrations as a plurality of points, the number of which is not less than four. A calibration curve is approximated by up to a fourth-order polynomial using a method of least squares based upon the measured values of not less than 4 points thus sampled. In carrying out the above-mentioned polynomial approximation, an inverse number of the square of the divided ratio at each point of the calibration curve is used so as to carry out a weighting operation.

摘要： An infra-red analyzer is fed with a series, of at least four, different gaseous compositions, comprising an inert diluent gas plus varying amounts of the calibration gas, the analyzer signals monitored and by the 'method of least squares' fitted to provide a calibration curve representing a fourth order polynomial equation. After obtaining the approximation of the squares a correction weighting is applied using the reciprocal for each of the obtained data points.

摘要： In a procedure for diluting samples for a chemiluminescence analysis apparatus, a gaseous sample is fed through a NOx sample gas line (2)to a NOx converter (3) in which the NOx content of the sample is converted to NO. The sample gas is diluted in the sample gas line (2) with an inert gas at a mixing point (13) which is upstream of the converter (3). Also claimed is a chemiluminescence apparatus.

摘要： PROBLEM TO BE SOLVED: To reduce time for allowing a calibration gas to contain a given amount of steam in an infrared gas analysis by performing humidification via a tube consisting of a semipermeable membrane for water transmission. SOLUTION: For example, an infrared ray type gas analyzing device for measuring the exhaust gas or the like of an automobile includes a humidifier 13 where a tube 12 formed of a semipermeable membrane inside, for example, at the upstream side of a dehumidifier 9 in a calibration gas supply path 1. Then, a calibration gas that is a zero gas Z and a span gas S is humidified while passing inside the tube 12 due to water or a humidification gas flowing in a chamber C of the humidifier 13 and is adjusted to a specific water concentration due to the dehumidifier 9 as needed. By providing a plurality of tubes 12 in parallel in the humidifier, much water can be contained in the calibration gas. For adjusting the amount of water to be transmitted, the length of the tube 12, the ambient temperature of the humidifier, and the like can be changed.

摘要： PROBLEM TO BE SOLVED: To provide a method for preparing calibration curve for infrared gas analyzer by which such a calibration curve that can reduce the systematic error resulting from the principle of measurement of an infrared gas analyzer as much as possible and can improve the measuring accuracy of the analyzer. SOLUTION: In a method for preparing calibration curve for infrared gas analyzer, the calibration curve of an infrared gas analyzer is prepared by collecting the four or more outputs of the analyzer corresponding to the then concentrations of a gas SG concentrations while the gas SG is supplied to the analyzer at different concentrations and approximating the calibration curve by quartic polynomials by using the method of least squares based on the four or more measured values. At the time of performing the polynomial approximation, the reciprocal numbers of the squares of the concentrations are used for weighting at each point of calibration curve preparing data.
