摘要： In analyzing the concentration of an objective component contained in a sample gas by a gas analyzer, an output of the gas analyzer is corrected at a fixed point by applying the relationship between the concentration of a coexistent gas and a span sensitivity of the objective component to make it possible to simply correct the effect of the coexistent gas. In addition, by inputting, at the time of the calibration of the gas analyzer, the information on to what extent the base gas composition differs from the average amount of the actual sample along with the concentration amount of the objective component in the calibration gas, the sensitivity adjustment coefficient is determined by taking into account the effect amount which is previously stored in the gas analyzer, by which the effect amount of the span sensitivity by the difference of the base gas compositions in the calibration gas and the sample gas is suppressed, and the effect of the coexistent gas is canceled to the best possible extent.

摘要： An exhaust gas measuring bag which can smoothly exhaust gas and perform back purge and back dump in a short period of time without leading to an increase in size and costs of the system is provided. The exhaust gas measuring bag includes a gas connection part which is connected to an external passage flowing measurement gas therethrough for analyzing various components included in the exhaust gas. A pipe is connected to an internal passage of the gas connection part and a plurality of gas ejection holes for ejecting the gas are formed on the pipe. A bag body is deformable and has an internal space for storing at least a connection side of the gas connection part to the pipe, and the whole of the pipe therein. The pipe encloses the gas ejected from the gas ejection holes into the internal space therein. A gas exhaust port is provided, at the gas connection part or a member separated from the gas connection part, and exhausts the gas enclosed in the internal space to the external passage. A valve is disposed on an exhaust passage connecting the gas exhaust port to the external passage, opens the exhaust passage at the time of exhaust of the gas, thereby allowing the gas to pass and closes the exhaust passage at the time of non-exhaust of the gas, thereby preventing passage of the gas.
