Abstract

Abstract The sources of error in gas chromatography have been tabulated and the precision of seven methods for the measurement of peaks has been compared. Of the methods tested the electronic integrator gives the highest precision provided the peaks are completely separated and provided stable baseline conditions apply. The use of peak height gave a comparable precision to that of the integrator and is less affected by long-term variations except where peak ratios are used. The use of manual construction for the measurement of peak area gave a low order of precision but the “peak height × width at half height” method was significantly better than triangulation methods.
