  • Publication number: 20220373523
    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.
