On-line sample preconcentration using field-amplified stacking injection in microchip capillary electrophoresis.
Previous reports describing sample stacking on microchip capillary electrophoresis (microCE) have regarded the microchip channels as a closed system and treated the bulk flow as in traditional capillary electrophoresis. This work demonstrates that the flows arising from the intersection should be investigated as an open system. It is shown that the pressure-driven flows into or from the branch ...
متن کاملClinical analysis by microchip capillary electrophoresis.
Clinical analysis often requires rapid, automated, and high-throughput analytical systems. Microchip capillary electrophoresis (CE) has the potential to achieve very rapid analysis (typically seconds), easy integration of multiple analytical steps, and parallel operation. Although it is currently still in an early stage of development, there are already many reports in the literature describing...
متن کاملHigh-sensitive analysis of DNA fragments by capillary gel electrophoresis using transient isotachophoresis preconcentration and fluorescence detection.
In this report aimed on further development of a high-sensitivity capillary gel electrophoresis (CGE) method for analysis of DNA fragments, we firstly explored online transient isotachophoresis (tITP) preconcentration combined with fluorescence detection (FD). The fluorescence signal (excitation: 488 nm; emission: 590 nm) was generated using the intercalating dye of ethidium bromide (EB). It wa...
متن کاملMicrochip capillary electrophoresis with electrochemical detection.
A novel microchip capillary electrophoresis system with electrochemical detection, using the replaceable microelectrode, is first reported. This kind of electrode can be fabricated in general laboratories and can be replaced quickly with electrodes of different materials according to the requirements of experiments. The end-column electrochemical detection on microchip CE was achieved by fixing...
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...
