  • Patent number: 10107829
    Abstract: The present invention is to present an analyzing method for analyzing a target substance contained in a sample using a reagent containing magnetic particles. The method comprises steps of: (a) magnetically capturing magnetic particles in a container with a first magnetic force generating member arranged on a lower side of the container accommodating a liquid specimen containing the magnetic particles; (b) transferring the container to a target substance separating section after the step (a); and (c) in the target substance separating section, discharging a cleaning liquid into the container and aspirating a liquid in the container while magnetically capturing the magnetic particles in the container with a second magnetic force generating member.

  • Patent number: 9255939
    Abstract: A sample analyzer comprises a pipette, a pipette moving mechanism and a position confirming member disposed at a position where the pipette can be moved by the pipette moving mechanism. The position confirming member comprises a space into which a tip end of the pipette can be inserted. When the sample analyzer carries out the position confirmation process, the tip end of the pipette is moved by the pipette moving mechanism so as to be inserted into the space of the position confirming member. When a sensor sensed that the tip end of the pipette collides with the position confirming member, the sample analyzer stops the movement of the pipette and notify that the pipette of the pipette moving mechanism has a problem.

  • Patent number: 9229018
    Abstract: The present invention is to present a sample analyzer for analyzing a target substance in a sample by carrying out a target substance separating process for separating a complex containing the target substance and a magnetic particle from other substances other than the complex. The sample analyzer executes the target substance separating process with respect to a second container held by a second holder with a second nozzle while executing the target substance separating process with respect to a first container held by a first holder with a first nozzle, and completes the target substance separating process with respect to the first container with the first nozzle and completes the target substance separating process with respect to the second container with the second nozzle.

  • Publication number: 20090226344
    Abstract: A sample analyzer is disclosed which enables to confirm the position of a pipette of dispensing section not depend on instruction directed a start of a position confirmation operation from the operator, and to prevent a pipette from being damaged or credibility of analysis results from declining. Concretely, the sample analyzer comprises a pipette, a pipette moving mechanism and a position confirming member disposed at a position where the pipette can be moved by the pipette moving mechanism. The position confirming member comprises a space into which a tip end of the pipette can be inserted. When the sample analyzer carries out the position confirmation process, the tip end of the pipette is moved by the pipette moving mechanism so as to be inserted into the space of the position confirming member.
