Limitations and how to avoid problems
Rinse Fraction
Collection Needle
If
Rinse Fraction Collection Needle
is set to
Between fraction collection
, at
least 0.3 min are required to perform this task.
When doing time-based fraction collection rinsing the needle is only possible
between two time table entries, which must have a gap of at least 0.3 min.
For peak-based fraction collection a time gap of also at least 0.3 min is
required. If a new peak is detected during the rinse process, it is aborted and
the needle moves back to the next free fraction position. Depending on flow
rate and delay volume V
D1
the beginning of this peak may be lost.
If you have recovery positions in your fraction collector or if you are using one
fraction collector for sample recovery in a multiple fraction collector
configuration, the rinse function
between fraction collection
is ignored.
Needle
Movement
The option
into location
under
Needle Movement
in the fraction collector
configuration must only be used for capped 2 or 5 ml vials or well-plates.
Using other or open vials with this command can lead to a
Movement failed
error.
Replacing
fraction
containers
When replacing filled tubes, vials or well-plates from the fraction collector
make sure to remove and re-insert the complete tray. Otherwise the fraction
collector will not recognize that the fraction containers were emptied.
Pooling
When pooling fractions, overfill protection no longer exists. It is the user's
responsibility to make sure that all fraction collection locations are large
enough to completely collect all pooled fractions. If a fraction collection
location is overfilled, an error message occurs and the pump is shut off.
