the continuing look for fast, effective and competitively priced technique of analytical dimension has brought supercritical fluids into the sphere of analytical chemistry. parts are universal: supercritical fluid chroma­ tography and supercritical fluid extraction. either search to take advantage of the original houses of a gasoline at temperatures and pressures above the severe aspect. the most typical supercritical fluid is carbon dioxide, hired as a result of its low serious temperature (31 °C), inertness, purity, non-toxicity and cheapness. substitute supercritical fluids also are used and infrequently along with modifiers. The mixed gas-like mass move and liquid-like solvating features were used for superior chroma­ tographic separation and speedier pattern instruction. Supercritical fluid chromatography (SFC) is complementary to gasoline chro­ matography ( GC) and excessive functionality liquid chromatography (HPLC), delivering better potency than HPLC, including the power to examine thermally labile and excessive molecular weight analytes. either packed and open tubular columns will be hired, delivering the potential to examine quite a lot of pattern kinds. additionally, flame ionization detection can be utilized, hence delivering 'universal' detection.
