A convenient procedure has been described for enhancing the sensitivity of equilibrium headspace gas chromatography. The technique involves the cryogenic focusing of headspace vapors at the head of a 0.32 mm fusedsilica capillary column which has been coupled to a packed column injection port. Cryofocusing is accomplished automatically by cooling the GC oven and results in enhanced sensitivity with improved resolution. With this simple focusing technique no sample splitting is required which gives at least a 10-fold increase in sensitivity. A Multiple Headspace Injection (MHI) technique has been described which allows several rapid headspace injections to be made at the start of a single chromatographic run. Cryofocusing causes the injections to be superimposed, thus increasing the sensitivity even further. These procedures have been demonstrated for flavor and aroma analyses of toothpaste and soft drink samples.
