MOLECULAR IMPRINTS FOR SOLID-PHASE EXTRACTION
2000Among the most important fields in analytical chemistry are medical, food and environmental analysis, where the target analytes are often present at very low concentrations in rather complex matrices. Methods currently used for analysis, such as liquid chromatography, gas, chromatography or capillary electrophoresis, must therefore be proceeded by a ...

Carbon nanotubes: Solid-phase extraction
Journal of Chromatography A, 2010Since the first report in 1991, carbon nanotubes (CNTs) have shown great possibilities for a wide variety of processes and applications, which include their use as electrodes, sensors (gas, enzymatic, etc.), nanoprobes, electronic materials, field emitters, etc. The combination of structures, dimensions and topologies has provided physical and chemical

Immuno-affinity solid-phase extraction
Journal of Chromatography B: Biomedical Sciences and Applications, 2000The measurement of trace organics such as drugs and pesticides at low concentration in biological and environmental samples is a challenging analytical task. Despite recent advances in instrumentation most analysts regard sample preparation as the rate-limiting step in the overall analytical method.

Solid-Phase Extraction in Malondialdehyde Analysis
Analytical Biochemistry, 1997Malondialdehyde (MDA) has been widely used as an index of lipoperoxidation in biological and medical sciences as well as in the food industry. A solid-phase extraction (SPE) of the condensation product of the MDA with 2-thiobarbituric acid (TBA) was developed using LiChrolut C18ec, 200 mg (Merck, Darmstadt, Germany), as a SPE cartridge and methanol as ...

A magnetizable solid phase for enzyme extraction
Applied Biochemistry and Biotechnology, 1991A method for the convenient and reliable preparation of magnetizable agarose beads containing iron particles is described. The beads were treated with the triazine dye, Reactive Red 120, and the matrix was examined for the ability to extract proteins from crude preparations using lactate dehydrogenase from porcine muscle as a model.

Graphitized carbons for solid-phase extraction
Journal of Chromatography A, 2000The objective of this review is to provide updated information about the most important features of graphitized carbonaceous sorbents used for solid-phase extraction (SPE) of organic compounds from liquid natural matrices or extracts. The surface characteristics of graphitized carbon blacks and porous graphitic carbons are described which are ...
