摘要

This invention involves an apparatus of outlet reservoir and a technique for performing large volume stacking using electroosmotic flow pump (LVSEP) in capillary electrophoresis-mass spectrometry (CE-MS), which is a simple method to achieve greater enhancement in detection sensitivity. This invention utilizes an apparatus which is placed between MS orifice and capillary outlet and allows to supply the flow of the run buffer in the direction opposite to sample injection during sample stacking. The capillary outlet and electrospray ionization emitter are immersed into the apparatus which is filled with the run buffer. This apparatus is in a manner that attachment and detachment are allowed between MS orifice and capillary outlet.
