Sampling gaseous compounds of heating essential oil using solid phase microextraction devices

5th International Conference and Exhibition on Analytical & Bioanalytical Techniques

Abstract
This investigation compared the extraction efficiency of needle trap samplers (NTS) with that of the commercial 100 μm polydimethylsiloxane-solid phase microextration (PDMS-SPME) fiber sampler when applied to sample heating products from tea tree essential oil. The experimental results indicated that NTS performed better effectiveness than those of SPME fiber sampler, and the NTS, packed with 80-100 mesh divinylbenzene (DVB) particles, primarily adsorbed 5.7 ng ethylbenzene, 5.8 ng m/p-xylenes, 11.1 ng 1,2,3-trimethylbenzene, 12.4 ng 1,2,4-trimethylbenzene and 9.99 ng 1,4-diethylbenzene when thermal ceramic wicks were used to evaporate the tea tree essential oil during 1-hr evaporation period.
