Summary
The object of the present study was to determine the usefulness of averaging data obtained from repeated analyses in improving reproducibility of the results, both in terms of retention indices and peak area percentages and to find an optimal compromise between reproducibility and total analysis time. All the necessary calculations are performed by an off-line computer system using a digital integrator and punched tape obtained by a teletype. The standard deviation and the 95% tolerance limits for each peak area percentage in a multiple analysis are readily provided. Stray values are eliminated by means of the t-test.
