Patent abstract
A method for controlling the flow of liquid in a high performance liquid chromatography apparatus. The method includes operating a pump, measuring the liquid pressure downstream of the pump, measuring the liquid flow rate downstream of the pump, and controlling the operation of the pump. In the method, it is automatically determined whether the pump is controlled to achieve a desired pressure or controlled to achieve a desired flow rate. Fuzzy logic can be applied in the method to determine the switch between the control modes.
