FRONT PANEL CONTROL
Basic Control Configurations
A 333 Pump can be used alone or as a master pump to control up to two other solvent pumps
(333 Pump or 334 Pump). It may also be used to command an injection pump.
NOTE
Additional solvent pumps are always connected hydraulically to the pressure, purge, and mixing
module (PPMM) of the 333 Pump.
Hydraulic Connections for Gradient or Isocratic Mixtures
The 333 Pump can be configured to control the flow and composition of the mobile phase on a
time variant (gradient) or a time invariant (isocratic) basis, when associated with a 334 Pump.
Thus, you can pump gradients using two solvents, or you can pump in isocratic mode after
mixing Solvent A (from one pump) and Solvent B (from the other).
For a binary gradient configuration, connect a 333 Pump to a 334 Pump. Solvent B is routed
via the outlet tee of the 334 Pump to an inlet on the PPMM of the 333 Pump, where the two
solvents are mixed. When three solvents (ternary) are to be combined, a second slave pump
can be connected to the PPMM.
