摘要： An exhalation collected in a breath bag capable of expanding and contracting is sucked into a gas inlet vessel 21 with a given volume (Va), and then the gas inlet vessel 21 is communicated by means of valve V2 with a cell 11 that is maintained at an atmospheric pressure by being pre-filled with a sample gas or reference gas. After the communication, the gas pressure is measured by a pressure sensor 16 attached to the cell 11. Whether the exhalation collected in the breath bag is below a given amount or not can be accurately judged.

摘要： In an isotopic gas analyzer, a gas injector (21) is provided for pressurizing a gas specimen in cells (11a,11b). The pressurization of the gas specimen virtually produces the same effect as increasing the concentration of carbon dioxide in the gas specimen, thereby improving an S/N ratio for the analysis and hence data reproducibility.

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.
