1. A sample analyzing method of analyzing a liquid specimen containing biological complexes formed from target substances bonded with magnetic particles, the method being carried out with a target substance separating process for magnetically separating the biological complexes from substances other than the biological complexes in the liquid specimen, the target substance separating process comprising steps of:
(a) receiving at a preliminary BF separator a container having an amount of the liquid specimen therein and performing at the preliminary BF separator magnetic separation on the received container, using a magnet arranged to the preliminary BF separator, to magnetically collect the magnetic particles at a location in the received container; (b) after the magnetic separation is performed at the preliminary BF separator, transferring the container by a container transfer unit from the preliminary BF separator to an available one of a plurality of ports; (c) executing the magnetic separation on the containers separately in parallel at at least some of the plurality of ports, using a group of magnets arranged, respectively, to the plurality of ports and each used to perform the magnetic separation on the container received at the corresponding port in order to magnetically collect the magnetic particles at a location in the container; (d) aspirating liquid from the containers separately in parallel at at least some of the plurality of ports, using a group of nozzles arranged, respectively, to the plurality of ports and each configured to discharge a cleaning liquid into and aspire liquid from the container received at the corresponding port; (e) discharging the cleaning liquid in the containers separately in parallel at at least some of the plurality of ports; and (f) repeating above steps (c), (d) and (e) at multiple cycles on each of the containers while it stays at its port. |
