Optimizing the Performance of the Device

General Guidelines
Integral Fraction Collector FT (VF-F20-A) Operating Manual
This section provides information for best performance of the device
and gives hints on what you can do to optimize the performance further.
To optimize the device performance, consider the following general
guidelines:
•
Leave the device doors closed during fraction collection processing
to avoid any interruptions.
•
Perform needle wash and rinse for lowest possible carry over. The
needle wash and needle rinse ensure that the needle is properly
cleaned from the remaining last fraction, both inside and outside of
the needle.
•
According to application purpose, flush function helps to achieve
both higher recovery and minimize carryover.
•
Before you switch the fraction collection valve, make sure that the
pump flow is turned on. Avoid switching the fraction collection valve
without flow, i.e. switching the fraction collection valve dryly.
•
Monitor the usage of specific device components that are subject to
wear and stress and schedule appropriate maintenance intervals.

•
Observe the general guidelines and recommendations in the
Vanquish System Operating Manual on the use of solvents and
additives in the chromatography system.
