•
Continue to pump water through the system for at least 10 minutes.
You may wish to continue fraction collection or return the
SV3-2 valve to position 1 and then stop fraction collection.
Note
: In
manual
operation, starting or stopping fraction collection
does not change the SV3-2 diverter valve position. You must always
manually set the SV3-2 valve to the waste or collect position.
b. Using a Model 2128 Fraction Collector.
The Model 2128 Fraction Collector has two operating modes:
•
System: Controlled by the BioLogic HR System.
•
Local: Controlled from its own faceplate.
For now, insure that the System button is selected.
When in System mode, operation of the fraction collector is as follows.
•
Control of the Model 2128 is identical regardless of whether or not
the optional on-arm diverter valve is used. Without a valve, the
drop-head returns to the waste trough during divert operations.
•
The fraction collector box on the manual screen will show fields
