Title:
APPARATUS AND METHOD OF USING BI-DIRECTIONAL CAPILLARY ELECTROPHORESIS
Document Type and Number:
WIPO Patent Application WO2004076497
Kind Code:
A9
Abstract:
The present invention provides an apparatus and method of utilizing bi-directional capillary electrophoresis ("CE") device 9. In one embodiment, cations are drawn into a first uncharged channel 23 towards a negative electrode 27 and anions are drawn into a second uncharged channel 24 towards a positive electrode 25. The uncharged channels 23,24 allows for minimal interaction between the sample and the walls of the channel 23,24 which allows for minimal sample loss. The present invention also provides a method of separating anions from cations. The method comprises delivering the mixture to a bi-directional CE device 9. Following delivery, cations are drawn into a first uncharged channel 23 towards a negative electrode 27 and anions are drawn into a second uncharged channel 24 towards a positive electrode 25. In one aspect of the present invention, the bi-directional CE device 9 engages a microfluidic proteome analysis system 31.
