Effects of modifiers in packed and open-tubular supercritical fluid chromatography
The applicability of packed and open columns for supercritical fluid chromatography using pure carbon dioxide for the elution of a number of selected test components was investigated. It is shown that the number of solutes that can be eluted as symmetrical peaks is much larger in open-tubular capillary supercritical fluid chromatography. For strong hydrogen donors and acceptors, however, poor p...

Nicole Riddell (2017): Packed Column Supercritical Fluid Chromatography: Applications in Environmental Chemistry. Örebro Studies in Chemistry 19. Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs). T...
متن کاملSupercritical Fluid Extraction+supercritical Fluid Chromatography
high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...
متن کاملGas Chromatography Application in Supercritical Fluid Extraction Process
There are two types of application for gas chromatography (GC) in the supercritical fluid extraction process. Gas chromatography is a type of supercritical extraction apparatuses which can separate a component from a multi-component mixture during supercritical extraction. Therefore, this application can be the alternative to conventional gas chromatography, which needs high temperatures for th...
