Chiral Separation of Basic and Zwitterionic Drugs by Highly Sulfated Cyclodextrins Using Short-End Injection Capillary Electrophoresis Highly Sulfated Cyclodextrins Using Short-End Injection Capillary Electrophoresis
Due to high resolution power of sulfated cyclodextrins (HS-CDs), utilization of these selectors for chiral resolution of 7 basic and 2 zwitterionic drugs have been examined. Experiments were performed on a HP3DCE instrument equipped with an on-column diode array UV absorbance detector. Fused silica capillaries with an inner diameter of 50 ?m, an outer diameter of 365 ?m, and a total length of 4...

متن کاملInkjet-based Dna Injector for Microchip Electrophoresis
We developed an inkjet-based DNA injector for microchip electrophoresis system based on a straight microchannel. The inkjet-based DNA injector enables us to precisely control injection volume of DNA and to use a simple straight microchannel for chip electrophoresis, whereas we need cross channel injector or T injector as well as complicated voltage programming for conventional chip electrophore...
متن کاملContactless conductivity detector for microchip capillary electrophoresis.
A microfabricated electrophoresis chip with an integrated contactless conductivity detection system is described. The new contactless conductivity microchip detector is based on placing two planar sensing aluminum film electrodes on the outer side of a poly(methyl methacrylate) (PMMA) microchip (without contacting the solution) and measuring the impedance of the solution in the separation chann...
متن کاملExperimental and Numerical Analysis of High-Resolution Injection Technique for Capillary Electrophoresis Microchip
This study presents an experimental and numerical investigation on the use of high-resolution injection techniques to deliver sample plugs within a capillary electrophoresis (CE) microchip. The CE microfluidic device was integrated into a U-shaped injection system and an expansion chamber located at the inlet of the separation channel, which can miniize the sample leakage effect and deliver a h...
