Field-portable Capillary Electrophoresis Instrument with Conductivity Detection
In this paper a novel capillary electrophoresis chip (CEC) is presented with integrated platinum electrodes and simplified conductivity detector. CEC is fabricated by the method of mechanical modification with probe on organic glass. Capillary electrophoresis chip can rapidly completed ion separation by simulation of concentration distribution and zonebroadening. Detection circuit is simple whi...
متن کاملPortable capillary-based (non-chip) capillary electrophoresis
Miniaturized, portable instrumentation has been gaining popularity in all areas of analytical chemistry. Capillary electrophoresis (CE), due to its main strengths of high separation efficiency, relatively short analysis time and low consumption of chemicals, is a particularly suitable technique for use in portable analytical instrumentation. In line with the general trend in miniaturization in ...
متن کاملOn-column conductivity detection in capillary-chip electrophoresis.
On-column conductivity detection in capillary-chip electrophoresis was achieved by actively coupling the high electric field with two sensing electrodes connected to the main capillary channel through two side detection channels. The principle of this concept was demonstrated by using a glass chip with a separation channel incorporating two double-Ts. One double-T was used for sample introducti...
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 کاملAnalytical instrument qualification in capillary electrophoresis.
Capillary electrophoresis (CE) is a well-established and frequently used technique in the pharmaceutical industry. Therefore an appropriate analytical instrument qualification (AIQ) is required for quality assurance. AIQ forms the basis of a quality management followed by analytical method validation, system suitability tests (SSTs) and quality control checks. Two parts of the AIQ, namely the o...
