By S. M. Hitchen, J. R. Dean (auth.), John R. Dean (eds.)

The endured look for swift, effective and low-cost technique of analytical dimension has brought supercritical fluids into the sphere of analytical chemistry. components are universal: supercritical fluid chroma­ tography and supercritical fluid extraction. either search to take advantage of the original homes of a gasoline at temperatures and pressures above the serious element. the most typical supercritical fluid is carbon dioxide, hired due to its low serious temperature (31 °C), inertness, purity, non-toxicity and cheapness. substitute supercritical fluids also are used and infrequently together with modifiers. The mixed gas-like mass move and liquid-like solvating features were used for better chroma­ tographic separation and swifter pattern practise. Supercritical fluid chromatography (SFC) is complementary to fuel chro­ matography ( GC) and excessive functionality liquid chromatography (HPLC), delivering larger potency than HPLC, including the facility to examine thermally labile and excessive molecular weight analytes. either packed and open tubular columns may be hired, supplying the aptitude to examine quite a lot of pattern kinds. furthermore, flame ionization detection can be utilized, hence delivering 'universal' detection.
