Gradient controller configuration
The controller allows these tasks in its gradient configuration:
• Controls isocratic or gradient solvent flow
• Controls output signals to external devices, internal alarms, sparge rate,
and linking operation with other tables while running a gradient
• Programs and runs Gradient tables that define varying solvent
composition, flow rate, time range, and rate of change for each phase of
the gradient
In gradient configuration, the controller does not communicate with any
PowerLine modules. Nevertheless, it can operate with any Waters data
system or integrator connected to the IEEE or RS-232 ports.
Operation
The Gradient controller stores 15 sets of tables. Each set consists of a
Gradient and an Event table. These run together during gradient operation.
The Gradient and Event tables can each include up to 15 operational steps.
