Summary For accurate determination of polar, high-boiling melissyl alcohol in mixtures containing also low-boiling components by capillary column gas chromatography with hot split injection, all experimental paramenters, such as the injection procedure, insert size and design, injector temperature, sample size, solvent and carrier gas nature, etc. must be optimized. Of the factors affecting the quantitation the nature of the insert packing material is of the greatest importance. With the commonly used packing material, quartz wool, in the insert, a much lower than true melissyl alcohol concentration was obtained. Accurate quantitation was only possible when stop-flow injection, together with an insert packed with glass beads was used.
