Isocratic, Binary and Quaternary Pumps
Dual pumps with precise feedback control design improve pressure stability
Quaternary system with innovative gradient proportional valve, gradient accuracy less than 1%
The core of the liquid chromatography system is a high-pressure pump, which is used to transport the mobile phase solvent and the sample to be measured into the chromatographic column. Rittun LC infusion pumps provide the pressure needed to overcome column resistance while providing stable pressure (pulsation-free) at precisely controlled flow rates.
Rittun liquid chromatography infusion pump combines a control algorithm and a dual-piston constant flow pump design to achieve precise flow and pressure control. The dual piston pump design integrates a primary pump to transfer fluid and a secondary pump working in series to control pulsation and flow rate. Rittun LC infusion pumps include overpressure and leak alarms to increase safety and pump reliability.
Isocratic Pump
· A two-stage pump for isocratic elution
Binary Pump
· Two two-stage pumps mix two mobile phases of different polarity in any ratio to produce isocratic or gradient elution.
Quaternary Pump
· Four-stage solenoid distribution valve can control the flow of 4 solvents with different polarities at low pressure
· A two-stage high-pressure pump delivers the combined liquid to the column.
· Use a quaternary valve in combination with a high-pressure pump to produce isocratic or gradient elution
