Dual stacking method combining large volume single drop microextraction and sweeping and the capillary for large volume single drop microextraction

摘要

The present invention combines the dual sample extraction method with a large volume of a single drop of fine sweeping method in capillary electrophoresis relates to a capillary method for the concentration and volume of a single large drop micro extraction . More specifically, the method and this in combination with the sweeping method to form a small amount of fine drops of the ends of the capillary in capillary electrophoresis, liquid phase micro extraction as it can form a stable form along with a large volume of fine droplets Oh ruler is an extremely low concentration of the sample or sample the concentration of the lines of the sensitivity thereof when the very increase of technical analysis .
