Abstract
An extensive gas chromatographic investigation of alternative stationary phases to polyethyleneglycol adipate has revealed two which are suitable for the quantitative analysis of hydrogenated and methylated natural and technical cashew nut-shell liquid. Relative response factors have been obtained for the saturated (15:0), monoene (15:1), diene (15:2) and triene (15:3) constituents of all the component phenols and have been used to correct the gas chromatographic results described in Part IV. A comparison has been drawn between the ionisation processes in the flame ionisation detector and in mass spectrometry.
