The various microextraction techniques have
been developed in order to reduce sample preparation
time, improve sensitivity and selectivity as well as to
corroborate the recent advances in the development of
highly sensitive and efficient analytical instrumentation.
The current trend is aimed at the simplification and
miniaturization of extraction steps, which has led to
the combination of multi-step extraction and analytical
analysis into single uninterrupted step. The method
development involves the screening and subsequent
optimization of both gas chromatography-mass
spectrometry (GC-MS) and solid phase microextraction
(SPME) parameters using multivariate experimental
design, which has been shown to be efficient and effective
with little experimental runs. The use of microextraction
has been very effective in the analysis of contaminants in
food, water and the environments to ensure they are safe
and does not pose any health risk to human.
