SUMMARY: Open-tubular gas chromatographic columns made from stainless steel tubing, coated with methyl silicone oil, give variable retention times for individual alcohols, dependent on the size of sample. This difficulty is largely overcome by using a small proportion of adsorption-reducing material with the methyl silicone. There are cases of reversal of peak order, caused by differences in column temperature or minor differences in the coating. However, with care, relative retention times are nearly constant and are helpful as an aid in identification of compounds. A procedure for precise comparison of the retention times of unknown fruit volatiles with known compounds is described. Relative retention times of representative compounds are given for twelve different stationary liquids.
