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.
