The volume fraction of gas mixtures may be measured gas chromatographically by application of the 100% method, provided they can be separated. In case of gases it is not necessary to calibrate with another method. The specific character of the detector signals can be eliminated by measurements with pure components. The procedure is compared with the Scholander method. In case of O2/N2 mixtures the results agree within reproducibility, but in case of O2/CO2/N2 mixtures a systematic deviation of the CO2 fractions to smaller values is found as concerns the Scholander method. A gas mixture with 5.6 Vol% CO2 shows a difference of approximately 0.3 Vol%. The gas chromatographic method is almost 100 times as sensitive as the Scholander method. High fractions may be measured without problems and the method is not restricted to O2 and CO2.
气体混合物的体积分数可以通过应用100%方法用气相色谱法进行测量，前提是它们能够被分离。对于气体而言，无需用其他方法进行校准。通过使用纯组分进行测量，可以消除检测器信号的特定特征。将该方法与施洛兰德方法进行了比较。对于O2/N2混合物，结果在可重复性范围内一致，但对于O2/CO2/N2混合物，与施洛兰德方法相比，发现CO2分数存在系统性偏差，向较小值偏移。含有5.6体积% CO2的气体混合物显示出约0.3体积%的差异。气相色谱法的灵敏度几乎是施洛兰德方法的100倍。高分数可以毫无问题地进行测量，并且该方法不限于O2和CO2。
