With the objectives of reducing the time necessary for an analysis and of improving the precision and accuracy of the analysis value, the isothermal gas-chromatographic optimum conditions were investigated and established. By the present method, the time necessary for an analysis is reduced to 25 min, from 35 min under the previous conditions, and both precision and accuracy are further improved together with an improvement of the calculation method of the calculation factors used in the calculation of the atomic ratio between C, H, O, and N. Thus many standard samples, including some liquid ones which are newly examined in this study, can be analyzed within an absolute error of about ±0.2%.
