ProElut™ LLE+ Cartridges
- ProElut™ LLE+ (Liquid-Liquid extraction)
- Classical liquid-liquid extraction using a separation funnel is often associated with certain disadvantages:formation of emulsion, poor phase separation, high solvent consumption, low degree of automation and high personnel cost. However, liquid-liquid extraction can be made more efficient by using ProElut™ LLE+cartridges. The simple and excellent performance of ProElut™ LLE+ cartridges eliminates emulsions and therefore results in higher recoveries and cleaner extractions.
- How do ProElut™ LLE+ work?
- The aqueous sample is applied to the ProElut™ LLE+ sorbent. It distributes itself in the form of a thin film over the chemically inert matrix and thus acts as a stationary phase. Subsequently, elution takes place using organic solvents that are nonmiscible with water, e.g. diethyl ether, ethyl acetate or halogenated hydrocarbons. All the lipophilic substances are extracted from the aqueous into the organic phase. During this process the aqueous phase remains on the stationary phase. The eluate is free from emulsions and can be evaporated for further analysis.
- Application of ProElut™ LLE+
- ProElut™LLE+ has been widely applied in the sample preparation of urine, whole blood, plasma, serum,gastric juice, liquor, amniotic fluid, and animal and plant tissue. Other applications are in the areas ofenvironmental and residue analysis, e.g. the analysis of industrial, domestic and waste water.
