Conditions for collecting volatile components on Porapak Q and desorbing them for gas chromatographic examination have been investigated using a synthetic mixture representing the aroma components of cider. Optimum recoveries and least errors were obtained using a piston displacement procedure, 32 mg of Porapak, a temperature of 150°C for 20 min for desorption and ratios of vapour to liquid not exceeding 5:1. Tenax GC gave more consistent results than Porapak Q for non‐polar compounds with boiling points greater than that of hexyl acetate.
