Title:
MICROCHIP ELECTROPHORESIS DEVICE
Document Type and Number:
Japanese Patent JP3661320
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To automate the operation of electrophoresis of a microchip.
SOLUTION: In a microchip 1 in a dry state, a sample injecting opening S1 and an electrophoresis liquid reservoir B1 are positioned at a location P, where a rod 13 is lowered and at a location I, where a needle 12 is lowered respectively by the movement of a tray 10 in Y directions. After the needle 12 and rod 13 are each lowered to the locations I and P on the microchip 1 to fill a separating channel 2-1 and sample introducing channel 3-1 with a electrophoresis liquid, A sample is injected into the sample injection opening S1 from a syringe 22. Then the needle 12 and rod 13 are raised, and the tray 10 on which the microchip 1 is fixed is again moved in Y directions to match the detection point Ml of the channels to the location of a part to be detected and to perform a regular analysis.
