Solid phase analytical derivatization as a sample preparation method

•Overview of sample preparation methods.•Overview of analytical derivatizations.•Applications of solid phase analytical derivatizations in analysis.•The mechanistic aspects of solid phase analytical derivatizations.

Analytical derivatization (AD) is an important procedure in analysis as it improves the sensitivity, selectivity and chromatographic separation. Solid phase analytical derivatization (SPAD) combines extraction and derivatization into a single step fulfilling many aspects of a good sample preparation technique, which includes low organic solvent consumption, economical, ease of automation with any chromatographic system and applicability in a wide range of complicated matrices. In this review we have focused on wide applications of SPAD when used in combination with different sample preparation methods, such as solid phase extraction, ion exchange resins, solid phase microextraction, in-tube, microfluidic devices, and hollow fiber extraction methods.
