抄録

In the gas chromatographic approaches for quantitative determination of the components under consideration, there have been various methods for evaluating peak areas of the chromatogram, namely, planimeter tracing, triangulation, half-band width method, peak height×retention time method, gravimetry by cutting out the peak areas, and automatically operated electronic integrator. The authors introduced a new parameter involving a multiple of the peak height by the time required for the deflection of the recorder pen from base line to the peak point. The parameter exhibited a superior linearity with the actual peak areas to all other parameters mentioned above except the electronic integrator and the linearity reproduced in widely different patterns of the chromatograms.<BR>It has been also found that most of the peak patterns of the chromatogram were well traced by the distribution function proposed by Levenspiel's mixing-diffusion model while the Gaussian and Poisson distribution functions could be applied only for chromatograms with sharp peaks. A geometric interpretation has been carried out with the linear relationship between the new parameter and the peak areas.
