Sample preparation is contemplated as constriction in the entire analytical process as it has its effect nearly on all later steps, and is interpretative for incontrovertible identification, corroboration, and quantification of analytes. To satisfy existing conditions in sample preparation for analytes at trace or ultra trace level in complex samples, new techniques have been devised for sample preparation. Current proclivity has involved: (1) automation via integrating sample preparation units and detection systems, (2) implementation of modern sorbents i.e. (nanomaterials), (3) application of greener perspective like solvent-reduced methods (e.g microextrartion methods). New techniques for sample preparation should be environmentally friendly but also it should be distinguished by their intelligibility of performance, as well as should be economical and time efficient. So, this review topic silhouette some of the key points regarding advancement in extraction/microextraction methods, considering these methods are widely perturbed and scrutinised.
