  • Patent number: 10476206
    Abstract: A short-canceling projection (35) has a support (36) and two plate-shaped insulating parts (37). With housings (10, 30) mated, the support (36) partitions two elastic contact pieces (24) of a short terminal (22). Plate-shaped insulating portions (37) protrude in opposite directions relative to the support (36), and, with the housings (10, 30) mated, enter between two female terminal fittings (12) and the elastic contact pieces (24) and cancel shorting between the female terminal fittings (12). Correction parts (41, 42, 43) are formed on the support (36) and the plate-shaped insulating portions (37) and make contact with the first housing (10) to displace the short-canceling projection (35) in the direction of approaching the short terminal (22).

  • Publication number: 20190145943
    Abstract: A chromatographic data system processing apparatus includes a liquid feeder, a sample injector, a column that separates samples, a detector, a controller that processes a detected result of the detector, and a data processor that examines and sets operations of the liquid feeder, the column and the detector, and a measurement condition. The data processor generates a three-dimensional graph having three axes related to a pressure, a time, and a number of theoretical plates based on data or variables indicating a relationship between the number of theoretical plates and a flow rate, and data or variables indicating a relationship between the pressure and the flow rate. The chromatographic data system processing apparatus can easily obtain a separation condition for obtaining performance from a three-dimensional graph including a pressure drop, a hold-up time and a number of theoretical plates.

  • Patent number: 10281439
    Abstract: In the present invention, differences in liquid feed properties between liquid chromatographic devices are determined, a liquid feed time table that takes these differences into account is acquired by way of system changes, and flow control is performed by a pump. Furthermore, the liquid feed time table after the system changes is divided into a plurality of intervals, and instructions are sent to the pump after approximate calculations are performed. Thus, by efficiently performing system change processes, the same measurement results can be obtained in a plurality of different liquid chromatograph devices, regardless of the differences in liquid feed properties.

  • Patent number: 9581573
    Abstract: A liquid chromatograph includes a liquid chromatograph unit that has a pump sending an eluent to a detector and a control unit that controls the liquid to be sent by the pump based on a predetermined time table. The control unit stores an elution response of the liquid chromatograph unit which is obtained when a predetermined command value is input and another elution response which is obtained when the same command value is input to another liquid chromatograph. The time table is converted in the control unit based on the elution response and the other elution response to obtain respective elution profiles. In this manner, even when a measuring method related to another liquid chromatograph is used, it is possible to provide a liquid chromatograph capable of obtaining measurement results which are the same as those obtained when the measuring method is used in the other liquid chromatograph.
