Superfluid chromatography

High performance hquid chromatography-mass spectrometry has been apphed to the determination of down to lmg L 1 of azo dyes in waste waters [37], Games et al. [38] used high performance hquid chromatography for solute focusing prior to superfluid chromatography-mass spectrometry in the analysis of waste streams. 

Maximum Working Pressure - (Pq) - The maximum working pressure of the detector determines the maximum impedance that can be permitted in post-detector conduits, valves or columns and is largely used in multidimensional analysis and superfluid chromatography. It is specified either in p.s.i or kg/m ... 

Von Bavel et al. [55] have developed a solid phase carbon trap (PX-21 active carbon) for the simultaneous determination of polychlorodibenzo-p-dioxins and polychlorodibenzofurans also polychlorobiphenyls and chlorinated insecticides in soils using superfluid extraction liquid chromatography for the final determination. Supercritical fluid extraction with carbon dioxide has been applied to the determination of dioxins in soil [114],...
