摘要

The electroosmotic flow mobility has been measured by the combination of monitoring the change in electric current dur ing electrophoretic run and operating the wavelet transform. Once the sample solvent zone with different ionic stenggth from background electrolyte migrated from the capillary, a sudden change in current could be observed from the ekectric current record of time history. The exact time (in the middle of abrupt range) corresponding to the abrupt change in cur rent was determined by wavelet transform. This work showed posed method was in a good agreement with the neutral mark er method commonly used.
