发明名称 CAPILLARY TYPE ISOKINETIC ELECTROPHORESIS DEVICE
摘要 PURPOSE:To detect quickly ions by providing a reference voltage between a migration start voltage of a blank and a detection voltage at which a terminal ion is detected and making the voltage in the stage of measuring a sample smaller than the reference voltage. CONSTITUTION:A migration tube 4 is divided from a sample chamber 3 side to a large-diameter part 7, a junction block 8 and a small-diameter part 9. A voltage is impressed between a terminal electrode 10 and a leading electrode 11 and the sample is migrated by the tube 4. The migration start voltage VS in the blank stage and the voltage VD at which the terminal ion is detected by a detector 5 are measured. The voltage VT when the terminal ions arrives at the block 8 is maintained between voltages VS and VT and is determined as the reference voltage. The migration voltage VM of the sample is made relatively large in the large-diameter part 7 and smaller than the voltage VT in the small-diameter part 9. The sample is coarsely divided in the large- diameter part and precisely in the small-diameter part and therefore the quick migration analysis thereof is made possible.
