Title:
FLOW CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2010094019
Kind Code:
A
Abstract:

To provide a flow controller which uses a combination of hydrostatic pressure and electroosmotic flow to control the flow of a fluid.

A driving fluid whose flow rate is dependent on both hydrostatic pressures and electroosmotic flow can be used (a) directly as a working fluid in an operable device, for example a chromatograph or (b) to move a working fluid 1203 from a storage container 625 to an operable device 1301, or can be used for both (a) and (b). The driving fluid 1204 can be composed of one or more fluids. Part or all of the driving fluid 1204 is passed through an electroosmotic device 100 so as to increase or decrease the flow rate induced by a hydrostatic pressure.
