抄録

Retention values of various samples read on chromatograms are transfered to logarithmic values on section paper using a logarithmic scale, and then read out as retention index values using equally divided scale. By sliding the scale, relationship between carrier gas flow rate and the retention values can be obtained, and relative retention values also calculated easily. For the description of the retention values, all the substances already recorded on the section paper can be used as an internal standard. Qualitative analysis is performed by comparing the peak position of the unknown sample containing an internal standard with that already recorded.<BR>Peak shapes of a certain number of effective plates can be expressed as equal width triangle. So, separation of peaks can be estimated merely by drawing a triangle of the number of effective plates at the position of the peaks on the section paper.<BR>The method is simple, but more useful than usual numerical expression.
