[Application of electroosmotic pump on micro column liquid chromatography].
An electroosmotic pump(EOP) was designed and evaluated, which could replace the mechanical pump. The EOP could generate 2.0 MPa-6.0 MPa output pressure and tens of nL/min-3 microL/min flow rate. A test mixture containing naphthalene, anthracene and phenanthrene was separated on a 14 cm x 320 microns i.d., 5 microns, C18 micro column with acetonitrile/water as a mobile phase, which demonstrated the applicability of the EOP.
