the ongoing look for fast, effective and good value technique of analytical dimension has brought supercritical fluids into the sector of analytical chemistry. parts are universal: supercritical fluid chroma tography and supercritical fluid extraction. either search to use the original homes of a fuel at temperatures and pressures above the severe element. the most typical supercritical fluid is carbon dioxide, hired due to its low serious temperature (31 °C), inertness, purity, non-toxicity and cheapness. replacement supercritical fluids also are used and sometimes together with modifiers. The mixed gas-like mass move and liquid-like solvating features were used for more advantageous chroma tographic separation and swifter pattern education. Supercritical fluid chromatography (SFC) is complementary to fuel chro matography ( GC) and excessive functionality liquid chromatography (HPLC), offering larger potency than HPLC, including the facility to examine thermally labile and excessive molecular weight analytes. either packed and open tubular columns might be hired, offering the aptitude to examine quite a lot of pattern forms. furthermore, flame ionization detection can be utilized, therefore delivering 'universal' detection.
