Waters 2545 Binary Gradient Module User Manual

Features 1-3
The two independent pump systems combine their two solvents at a filter/tee,
where the solvent mix is plumbed to the sample manager or another
component of the AutoPurification System.
MassLynx™ software controls the ratio of the two solvents by varying the
relative flows of pump A and pump B. The binary gradient module receives
pressure data from a pressure transducer associated with each pump head.
The firmware measures the individual pump head pressure during the
pumping cycle and adjusts the precompression to ensure consistent solvent
delivery and minimize pump-induced detector baseline disturbances.
The MassLynx interface with the binary gradient module also provides useful
diagnostics and troubleshooting routines.
Leak management
All fluid-handling areas of the binary gradient module contain leak routing
capability. Spilled solvent is routed to the drain tube below the front panel.
The optional leak sensor should be installed on the leak sensor bracket in the
drip tray.
