Document Type and Number:
WIPO Patent Application WO/2013/069769
Kind Code:
A1
Abstract:
In the present invention, when injecting a sample into carrier-solution channels (3A, 3B), injection shock is prevented. An upper wall and a lower wall of a sample injection part (11) of the carrier-solution channels (3A, 3B) comprise septums (13, 14). A needle (27) can vertically penetrate the septum (13) on the upper wall side and also penetrate the septum (14) on the lower wall side. A needle moving unit (28) causes the needle (27) to penetrate the septum (14) on the lower wall side and causes the tip of the needle to face the inside of a sample vessel (26). A measuring pump (29) is caused to suction and as a result a sample is sucked into the needle (27). Next, the needle (27) is extracted from the septum (14) on the lower wall side, the tip of the needle is caused to face the inside of the sample injection part (11), the measuring pump (29) is caused to discharge and as a result the sample within the needle (27) is injected.
