  • Gradient generation control for large scale liquid chromatography
    Patent number: 5089124
    Abstract: Precise gradient control is accomplished using a high flow three-way valve, appropriate mixing, and precise metering control. Gradient elution profiles are generated for flow rates above 100 ml/min. Control involves precise selection of two solvents, and correction factors for valve lag times and pump/valve synchronizations. The gradient is controlled simultaneously with other non-timed operations through a single microprocessor controller.
