SUPER CRITICAL FLUIDS IN ANALYTICAL CHEMISTRY

This review provides an updated discussion on the recent developments and applications of supercritical fluid technology in analytical chemistry. Supercritical mediums are usually used for extraction and separation of varied analytes in analytical science. SFE is suitable for recovery of varied analytes, especially non-polar organic compounds, from different matrices. However, via some modifications or by the help of modifiers or a chelating agent, this system might be successfully applied within the extraction of polar or maybe ionic analytes. The range of analytes extracted via SFE is wide and mostly includes food and pharmaceutical samples, pollutants extraction and metal cation extraction. The aim of this paper is to review, from analytical chemistry standpoint, recent advances within the use of SC-CO2 for the extraction and separation of analytes. At an equivalent time, a critical assessment are going to be made from the benefits of SCF technology as compared with traditional methods. The potentials, advantages, shortcomings, and prospects employed of supercritical fluids for separation and extraction of varied analytes also are considered. The efficiencies of SFE for the extraction of varied analytes from solid and aqueous samples are compared to traditional methods like Soxhlet extraction. Supercritical fluid extraction thanks to various reasons like its greenness, rapidity and high efficiency are widely used an alternate to standard solvent-based extraction methods. Also, SFE are often as an automatic and miniaturized extraction technique, since it reduces the amounts of required samples considerably. SFE avoids multi-steps of conventional methods (such as partitioning, clean-up, evaporation) and hence it can reduce the uncertainty within the results. Furthermore, SFE reduces analysis times and is a smaller amount laborintensive.
