Description:
This command monitors solvent consumption.
Function:
Before starting a sequence, enter the existing volume of each solvent component. Based on the flow rate and the solvent composition, Chromeleon calculates whether the amount of available solvent is sufficient for the sequence.
Parameters:
Value
Available volume of the corresponding component in [l].
LowerLimit
Lower limit for the corresponding component in [l]. If this value is reached, the batch is aborted and the following message appears:
[Abort] xx:xx:xx {Pump} The %A level is below the limit (x l)! Please refill %A.
Tips:
In the emergency program, reduce the flow rate to 0 ml/min. This ensures that the pump and the detector cell never run dry.
With UltiMate 3000RS, SD and BM pumps, the pump flow is stopped automatically if the lower limit is reached (requires pump firmware version 2.21 or later).
Tip:
Chromeleon checks the expected demand for solvent during the Ready Check. If not enough solvent is available, a warning is displayed.
