毛细管电泳（capillary electrophoresis）英文
The heart of capillary electrophoresis (CE) is electroosmotic flow (EOF). This is the mobile phase “pump” in
CE. Unlike gas chromatography (GC), there is no pressurized gas acting as the mobile phase in CE. Unlike high
performance liquid chromatography (HPLC) these is no (high pressure) pumped mobile phase. And unlike
paper chromatography, there is no capillary action that pulls the solvent through the stationary phase. Instead,
the electrical potential maintained across the CE’s capillary tube by the electrical circuit of the 1) capillary, 2)
buffer, 3) reservoirs, 4) electrodes, and 5) power supply sets up some pretty interesting conditions that makes
the buffer solution flow from one buffer reservoir to the other, just as if it were being pumped. This flow is
called electroosmotic flow.
