6.8 Vial Pusher Positions
There are two positions for the vial pusher during operation: AboveVial
and InVial . During shipment the pusher is in the InVial position. The
default setting in Chromeleon is also InVial .
For optimal collection performance for AboveVial mode, the default
distance between needle tip and the top of the sample container is 2
mm with needle tip protruding out of the pusher as the lowest point of
the whole needle unit.
For InVial mode the pusher needs to be the lowest point. The purpose is
to hold the vial down when the needle is pulled out from the vial septa.
Between different injections in one sequence, the system will detect if
the physical pusher position aligns with needle positioning mode. If not,
Chromeleon will issue a message to remind users to adjust to correct
position. For more information, refer to
Chromeleon Help .
