PURPOSE:To know the washing state of capillary on the way of washing. CONSTITUTION:An electrode 2 and one end of a capillary 1 are inserted in a vial 9 in order to supply a washing solution or a buffer solution into the capillary 1 and the vial 9 is hermetically closed to be pressurized. A voltage contact 2 or a flow voltage measuring contact 21 comes into contact with the electrode 2 and the electrode 3 on the other end side of the capillary 1 is connected to a high voltage power supply 5 or a voltage measuring device 25 through a changeover relay 6. The washing solution in the vial 9 is pressurized to be allowed to flow in the capillary 1 and the flow voltage accross the electrodes 2, 3 is measured by the voltage measuring device 25. When the flow voltage becomes a steady state, washing operation is completed. |
