Description
Used for optimizing the switch valve timing. It is
recommended to optimize the timing of switch
valve (Buffer valve) when wavy gradients are ob-
tained or when fluctuations in the step gradient
are observed during either system performance
tests or chromatography runs. Available options:
Switch valve timing A (default): to set switch
•
valve timing to 4 sec.
Switch valve timing B : to set switch valve
•
timing to 5 sec.
Advanced timing: to set the switch valve tim-
•
ing to any value from 3.0 to 5.0 sec (0.1 sec
increments).
For exporting details on the running condition of
the UV, Pump, pump tubing, all the solenoid valves
