Capillary zone electrophoresis (CZE) and matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) are two techniques highly suitable for the separation and detection of intact proteins. Herein, based on the use of a recently introduced iontophoretic fraction collection interface for the coupling of CE and MALDI-MS, the potential of the combination of both techniques for the anal...

Electrokinetic remediation has been increasingly used in soils and other matrices for numerous contaminants such as inorganic, organic, radionuclides, explosives and their mixtures. Several strategies were tested to improve this technology effectiveness, namely techniques to solubilize contaminants, control soil pH and also couple electrokinetics with other remediation technologies. This review...

In this paper, an improved bounce-back boundary treatment for fluid systems in the lattice Boltzmann method [Yin, X.; Zhang J. J. Comput. Phys. 2012, 231, 4295–4303] is extended to handle the electrokinetic flows with complex boundary shapes and conditions. Several numerical simulations are performed to validate the electric boundary treatment. Simulations are presented to demonstrate the accur...

A mathematical model and computer code for simulat ing electrokinetic fluid and sample manipulations in microfabricated fluidic devices (microchips) are described. The model accounts for mass transport mechanisms such as electrophoretic migration, bulk fluid motion due to electroosmosis, and diffusion. The interactive computer program implementing the model is capable of handling different chan...

• Charged polymeric membranes are characterized by transmembrane streaming potential. Polymeric membrane structure can be affected a pressure application. Sequential difference doesn´t affects surface charge. hydraulic permeability. The effect of on the electrokinetic properties different charged is analysed. Electrokinetic characterization involve application increasing or decreasing differenc...

A new, rapid and simple method is described and applied to resolve and quantify mixtures of prednisolone acetate, sulfacetamide and phenylefrine. The determination was accomplished by micellar electrokinetic capillary chromatography (MEKC) using a fused silica capillary (57 cm x 75 microm ID). The separation was carried out at 25 degrees C and 30 kV, using a 5 mM phosphate-5 mM borate buffer ad...

Microchip electrophoresis (ME) has emerged as a promising tool for rapid analysis of various sample types and it is one the most important modules miniaturized total systems. Electrokinetic effects provide both efficient transport separation components in microfluidic channels. Moreover, miniaturization devices drastically reduces reagent consumption, significantly decreases time, allows easier...
