In-tube solid-phase microextraction (IT-SPME) was developed about 24 years ago as an
effective sample preparation technique using an open tubular capillary column as an …

This review will attempt to provide an overview as well as a theoretical and practical
understanding of the use of microextraction technologies for drug analysis. The majority of …

Most sample-enrichment procedures currently available rely on adsorption of the analytes of
interest by a suitable adsorbent material. Although good performance can be obtained for …

Chromatographic methods are preferred in the analysis of organic molecules with lower
