The apparatus for the sequential electrophoretic analysis of clinical, food, environmental and industrial liquid samples of the invention comprises a dispenser for continuously dosing samples into a separation capillary with a flow line for the base electrolyte. The dispenser is connected to the outlet of the filling device.
The apparatus also has a contactless conductivity detector through which the separation capillary passes and is led to an end vessel with a high voltage electrode and connected to an under-pressure source. A grounding electrode is in the dispenser and is also connected to a time meter between two drops of the flow rate of the basic electrolyte.
