L-3245 Quaternary Pump
The core of the liquid chromatography system is the pump, which is used to transport the mobile phase solvent and the sample to the column. The chromatographic infusion pump provides the pressure needed to overcome the resistance of the column, while providing a stable pressure (no pulsation) at a precisely controlled flow rate.
The quaternary gradient pump combines the control algorithm and the design of double plunger constant flow pump, which can achieve accurate flow and pressure control. It includes overpressure and leakage alarm to improve the safety and reliability of the pump.
Technology Advantage
Four stage solenoid distribution valve can control the flow of four solvents with different polarity under low pressure
A two-stage high-pressure pump can transfer the combined liquid to the column.
The combination of quaternary valve and high-pressure pump can produce Isocratic or gradient elution
The quadron pump achieves efficient mixing and continuous delivery of the mobile phase through multi-channel design, precision control and dual-piston operation, and is one of the core components of the high-performance liquid chromatograph. Quadron pumps are widely used in the fields of environmental and food analysis, and their high accuracy and stability make them an indispensable component in high performance liquid chromatography analysis.
