Technical Abstract: Solid-phase microextraction, SPME, has been used in a number of fields for sampling volatile and semi-volatile compounds. SPME is a technique that does not involve extensive sample preparation, and can be applied to a range of analytes by employing different fiber coatings. Host emanations from humans or animals consist of a variety of compounds and are important in mosquito attraction. In previous studies in our lab, polar to nonpolar compounds of moderate volatility from human skin emanations were analyzed by thermal desorption of cryofocused glass beads using GC/MS, whereas a purge and trap system was employed for the detection of nonpolar to moderately polar compounds of high volatility.
