SAMPLE PROCESSING DEVICE AND SAMPLE PROCESSING METHOD

摘要

Such solution as a cleaning liquid can be passed quickly and reliably through a separation column of nozzle tip or the like having a solid phase to improve the throughput. A sample processing device comprises a separation column having a carrier capable of arresting an object substance, a liquid feed flow channel capable of feeding a liquid from one end side to the other end side of the separation column, and a communication flow channel disposed independently of the liquid feed flow channel and capable of allowing communication between the inside and outside of the separation column, wherein the communication between the inside and outside of the separation column provided by the communication flow channel is controlled.
