Cg. Fu et al., A NEW METHOD FOR DETERMINATION OF ELECTRO OSMOTIC MOBILITY USING SAMPLE ZONE AS A MARKER, Gaodeng xuexiao huaxue xuebao, 19(1), 1998, pp. 53-55
A new method for the determination of the electroosmotic mobility was
presented in this paper. The ''sample zone'' itself was used as a mark
er of the electroosmotic flow. The elution time of the sample zone fro
m the capillary was derived from the position of the electrophoretic c
urrent step. Based on it the mobility of electroosmotic flow can be ca
lculated. The results was well in agreement with those of the neutral
marker method. Furthermore, the present method was easy to operate and
need no additive equipments.
