Recent trends in sorption-based sample preparation and liquid chromatography techniques for food analysis.

摘要: The accelerated rising of the world's population increased consumption food, thus demanding more rigors in control residue and contaminants food-based products marketed for human consumption. In view complexity most food matrices, including fruits, vegetables, different types meat, beverages, among others, a sample preparation step is important to provide reliable results when combined with HPLC separations. An adequate before chromatographic analysis mandatory obtaining higher precision accuracy order improve extraction target analytes, one priorities analytical chemistry. recent discovery new materials such as ionic liquids, graphene-derived materials, molecularly imprinted polymers, restricted access media, magnetic nanoparticles, carbonaceous nanomaterials, provided high sensitivity selectivity an extensive variety applications. These well their several possible combinations, have been demonstrated be highly appropriate analytes complex samples products. main characteristics application these will presented discussed this paper. Another topic review covers advantages limitations microtechniques, off-line on-line combination analysis.
