5.6.3 Setting a Gradient Curve
For ramp gradients and multi-step gradients, you can specify linear or non-linear (curved)
gradient profiles. The gradient profile (curve) is set in the program.
1. Create a program with the Program Wizard (

page 68).
2. On the Pump Options page, select Ramp or Multi-Step Gradient on the Gradient
Type list.
3. On the Flow Gradient Pump Options page, enter the preferred curve (1 through 9) in
the Curve box.
Curve 5, which is the default setting, is linear. Changes in composition of the delivered
solvent over time are constant. Curves 1 through 4 are convex upward. Curves 6 through
9 are concave upward. For more information about gradient curves, see the Chromeleon
Help.
5.6.4 Liquid Level Monitoring for Solvent Reservoirs and Waste Container
Chromeleon features functions for solvent consumption monitoring and for monitoring the
liquid level in the waste container. The following properties are available, for example, in
the
Commands dialog box for the pump:
Solvent Reservoirs
(X = A, B, C, or D) Description
%X_Level Enter the following information for the related component of the solvent:
Value The volume at the beginning of the sequence.
LowerLimit The lower limit.
If the liquid level in the solvent reservoirs reaches the lower limit and
- an emergency program is available in Chromeleon, the pump is stopped as
defined in the program.
-
no emergency program is available in Chromeleon, the batch is aborted,
the pump flow is stopped, and the related message appears.
%X_WarningLimit Set the limit when you want to be informed about the liquid level in the
solvent reservoir. The input is in percent and refers to the lower limit.
A message appears when the liquid level is below the lower limit plus the
warning limit (= %X_Level.Lowe %X_WarningLimit).
%X_Remain Time Reports the time left until the liquid level is expected to reach the lower limit.
The time is calculated from the current flow rate and the volume entered for
%X_Level.Value.
