ことを特徴とする微流量グラジエント。 In a liquid chromatograph consisting of an eluent, a liquid pump, an inlet, a column, and a detector, a low-pressure mixing gradient is used that changes the mixing ratio by opening and closing multiple solenoid valves under normal pressure, and the flow rate of multiple pumps is adjusted. For high-pressure mixing gradients that change the mixing ratio, we installed a T-tube to split the flow rate between the mixer at the pump outlet and the sample injection port, and added a suction pump to enable gradients in the low flow rate range. Features a micro flow gradient.
