料導入装置。 In a switching valve where flow holes for connecting multiple flow paths and switching grooves connecting between the flow path holes face each other to switch the flow paths, the distance between the connecting flow holes and the flow holes is The sample suction valve also has a long switching groove that connects the connecting channel holes quickly and minimizes the time to shut off the channel, thereby suppressing pressure rise.
A sample introduction device characterized by switching a discharge flow path and suppressing a rise in pressure due to the flow path being blocked at the time of switching.
