Abstract: The present invention relates to technology which extracts a specimen in a microextraction method without droplets in capillary electrophoresis and analyzes. The present invention does not form micro-droplets at the end of capillaries but forms an organic layer membrane at the end of capillaries thereby using a 3-phase method or uses a 2-phase method which fills some specimens such as pentanol into the end portion of the capillaries and collects the specimens herein thereby performing electrophoresis. According to the present invention, efforts for a droplets-forming process and maintenance are not required and analysis is simply and automatically performed. In addition, by using various differences of 2-phase, 3-phase, an acceptor, and a donor, it is possible to variously expand the use of droplets microextraction.

Abstract translation: 本发明涉及在毛细管电泳和分析中以微萃取法提取样品而无液滴的技术。 本发明不会在毛细管末端形成微滴，而是在毛细管末端形成有机层膜，从而使用三相方法，或者使用将一些标本例如戊醇填充到端部的二相方法 的毛细血管并收集样本，从而进行电泳。 根据本发明，不需要用于液滴形成处理和维护的努力，并且简单且自动地执行分析。 此外，通过使用2相，3相，受体和供体的各种差异，可以不同地扩大液滴微萃取的用途。
