Feb 23, 2018A new high-capacity flotation technology, the StackCell, has been developed as an HydroFloat and StackCell systems radically improve separation and be used to add capacity or be used as a rougher in a tradition Column Cell Flotation. Development of a flotation method for preconcentration-separation .
A new, simple, rapid and sensitive solid phase extraction procedure based on separation and preconcentration of trace levels of allura red in water samples on MCI GEL CHP20P column system has been established.
A separation/preconcentration of aluminum (III) (Al3 ) has been developed to overcome the problem of high matrix species, which may interfere with the determination of trace quantity of
demand that preconcentration alternatives such as dense medium separation (DMS) be explored, to reduce the consumption of power and water on a plant, with the final objective of improving overall project economics. optimize value on new projects or existing operations.
Abstract. Abstract Separation of enantiomers represents an extremely important task in the field of analytical chemistry. This paper contributes to the field of the on-line preconcentration of enantiomers by developing a novel setup based on the electrokinetic accumulation of ketoprofen enantiomers on the pH boundary followed by enantioselective mobilization by a mixture of SDS, sulfated-β
Jamali, M.R.; Assadi, Y.; Shemirani, F.; Salavati-Niasari, M. Application of thiophene-2carbaldehyde-modified mesoporous silica as a new sorbent for separation and preconcentration of palladium prior to inductively coupled plasma atomic emission spectrometric determination.
A simple, sensitive, facile and low cost methodology, combined with flame atomic absorption spectrometry (FAAS), was employed to evaluate the selective separation and preconcentration of Pd(II) ions in environmental samples by using a triazole derivative as an organic coprecipitating agent without a carrier element.
The new technology can be effectively applied to the interior of small-diameter capillaries to in situ create surface-bonded stationary phase coatings and monolithic beds for a wide range of analytical separation techniques including GC, HPLC, SFC, CZE, and CEC.
Separation and purification Separation and purification, in chemistry, separation of a substance into its components and the removal of impurities. There are a large number of important applications in fields such as medicine and manufacturing. Since ancient times, people have used methods of separating and purifying chemical

Its separation principle is based on the differential migration of the ionic micelles and the bulk running buffer under electrophoresis conditions and on the interaction between the analyte and the micelle.
Abstract The main aim of this chapter exactly characterizes the contribution. The analytical chemistry of the rare earth elements (REEs) very often is highly complicated and the determination of a specific element is impossible without a sample pre-concentration.

ultra-trace monitoring of copper in environmental and biological samples by inductively coupled plasma atomic emission spectrometry after separation and preconcentration by using octadecyl silica membrane disks modified by a new schiff's base
The invention relates to a method for separating magnetic particles from a composition in a vessel. In the method, particles are first concentrated on the wall of the vessel and collected from this area by using a separation means (1) to which the magnetic particles adhere.
Abstract We have developed a new method of the separation, preconcentration, and determination of Cr(III), Cu(II), Cd(II) and Pb(II) ion in water samples. It is based on the use of activated carbon that was modified with rhodamine 6G to yield a solid-phase sorbent.
