Modern automated microextraction procedures for bioanalytical, environmental, and food analyses.
Journal of Separation Science, 2023Sample preparation frequently is considered the most critical stage of the analytical workflow. It affects the analytical throughput and costs; moreover, it is the primary source of error and possible sample contamination.

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 the published reports to date focus on the use of fibre solid-phase microextraction and so the review is significantly focused on this technology.

Headspace Solvent Microextraction
Analytical Chemistry, 2001A hanging microliter drop of 1-octanol is shown to be an excellent preconcentration medium for headspace analysis of volatile compounds in an aqueous matrix by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). Model compounds benzene, toluene, ethylbenzene, and o-xylene (BTEX) are conveniently and rapidly preconcentrated in the ...
