摘要： A correction curve (FIG. 19) is prepared by plotting .sup.12 CO.sub.2 concentrations and .sup.13 CO.sub.2 /.sup.12 CO.sub.2 concentration ratios which are determined on the basis of a calibration curve and .sup.13 CO.sub.2 and .sup.12 CO.sub.2 absorbances of gaseous samples having the same .sup.13 CO.sub.2 /.sup.12 CO.sub.2 concentration ratio but known different .sup.12 CO.sub.2 concentrations. A gaseous test sample containing .sup.13 CO.sub.2 and .sup.12 CO.sub.2 as component gases is introduced into a cell, and spectrometrically measured. A .sup.12 CO.sub.2 concentration of the gaseous test sample is determined by way of the spectrometric measurement. A concentration ratio correction value is obtained on the basis of the correction curve and the .sup.12 CO.sub.2 concentration of the gaseous test sample thus determined. A measured .sup.13 CO.sub.2 /.sup.12 CO.sub.2 concentration ratio is divided by the concentration ratio correction value thus obtained for correction of the .sup.13 CO.sub.2 /.sup.12 CO.sub.2 concentration ratio. Thus, the measurement accuracy of the concentration ratios of the component gases can be improved. A breath sampling bag and gas measuring system is also disclosed where each is configured such that breath inlets of the gas measuring apparatus are prevented from being respectively connected to the wrong breath introduction pipes of the breath sampling bag.

摘要： As previous processing of measurement in which gas to be measured containing, as gas components, carbon dioxide 13CO2 and carbon dioxide 12CO2, is introduced into a cell, and in which the intensities of transmitted lights having wavelengths suitable for measurement of the respective gas components, are measured and then data-processed to measure the concentrations of the gas components, the air having a predetermined volume Va is sucked by a gas injection device 21, a gas exhaust valve V6 of a cell 11 is closed and the air stored in the gas injection device 21 is transferred to the cell 11 filled with the air at an atmospheric pressure, thereby to pressurize the cell inside. The pressure thus pressurized is measured as P. The cell volume Vc is subtracted from the product obtained by multiplying the sum. V0 of the volume Va and Vc the cell volume Vc, by the ratio P0/P in which P0 is the target pressure of the gas to be measured at which a calibration curve has been prepared for an isotope gas analysis and measurement, thus determining the one-time gas injection amount of the gas injection device 21. Thus, measured concentration variations based on changes in atmospheric pressure can be corrected.

Thus, the measurement accuracy of the concentration ratios of the component gases can be improved.

摘要： A rotary stand (11) having a half-mirror (8) and a photodetector (10) mounted thereon, is continuously rotated around a first rotary shaft (A) passing through a sample (S), and set to a predetermined scattering angle. Simultaneously, a rotary reflecting mirror (7) is rotated at a predetermined angle to direct a reference li8ght (LR) to the half-mirror (8) at all times. The half-mirror (8) is also rotated at its own axis at a predetermined angle so that the direction of a scattering light (LS) at the light emitting side of the half-mirror (8) is identical with the direction of the reference lilght (LR). Accordingly, the reference light may be composed with the scattered light at an arbitrary scattering angle, enabling observation of the Doppler shift in the scattered light direction (FIG. 1).
