The low flow pumps consist of two identical pumping units in a single housing. They generate gradients by high-pressure mixing. A solvent selection valve provides flexibility in the choice of solvents.
Mobile phase composition is produced by mixing the outputs of pumphead A and B. The solvent selection valve allows the pumphead A output to originate from either channel A1 or channel A2. The pumphead B output may originate from either channel B1 or channel B2.
In order to deliver fast gradients over the whole composition range, the two pumpheads deliver a primary flow of 200 – 1100 μL/min from which a mass flow sensor controlled electromagnetic proportioning valve (EMPV) splitthe set column flow. Excessive solvent is diverted to waste. This electronic flow control automatically compensates for changes in solvent properties and backpressure throughout a run.
Solvent degassing is not done directly in the pump. A 4-channel, low volume micro vacuum degasser, available as a separate module, provides degassed solvents to the pump channel inputs. Solvent degassing is required for best flow stability and detector stability, especially at the low flow rates required to run capillary/nano LC applications.
