Patent number: 6156195Abstract: The object of the present invention is to provide a method for separating components in a liquid specimen and an apparatus used in said method, by which it is possible to avoid carryover even when the specimen injector is not washed using washing solution and also to avoid the increase of inner pressure in column of the separation device or ineffective separating operation even when many liquid specimens are separated by many times using the same separation device. In the present invention, the liquid specimen is introduced into the separation device from a direction opposite to eluting direction of the separation device which retains an adsorbent, and by separating and eluting the specimen from eluting outlet together with the eluant, trace quantity of insoluble substances and the specimen remained on the specimen introducing passage can be removed by elution procedure.Type: GrantFiled: March 26, 1998Date of Patent: December 5, 2000Assignees: Shimadzu Corporation, Wako Pure Chemical Industries, Ltd.Inventors: Kenji Nakamura, Shinji Satomura, Masayoshi Hayashi, Hideyoshi Arashima, Tetsushi Okuyama, Nobuhiro Hanafusa, Koji Tanimizu

Patent number: 5439646Abstract: A plurality of measuring modules are arranged on a table of a reaction part. The measuring module has one removable cell, and is provided with light sources and photodetectors. In proximity to the reaction part is a cell transfer part for mounting and dismounting the cell on and from the measuring module, a sampling probe for dispensing a sample into the cell, and a reagent probe for dispensing a prescribed reagent into the cell in response to a measurement item. A time from supply of each cell or dispensing of each sample to or in the reaction part to dispensing of a first reagent is controlled to be constant with no regard to the measurement items.Type: GrantFiled: September 15, 1993Date of Patent: August 8, 1995Assignee: Shimadzu CorporationInventors: Koji Tanimizu, Toshimi Kadota

Patent number: 5207986Abstract: A rack supply part, an analysis unit part and a rack storage part are formed as units which are separable from each other, and a rack carrier part is integrally mounted on the analysis unit part. The respective units are provided with locating members for coupling the units in a direction for transferring a sample rack.Since the rack carrier part is integrated with the analysis unit part, relative positional relation between a position for stopping the sample rack and a position for stopping a sample dispensing pipetter provided in the analysis unit part for attraction is not displaced even if the units are separated from each other and then recombined with and mounted on each other. Thus, location is easy and no fine adjustment of positional relation is required.Type: GrantFiled: March 26, 1991Date of Patent: May 4, 1993Assignee: Shimadzu CorporationInventors: Toshimi Kadota, Koji Tanimizu
