Rack Settings
If the option Exchange rack if full is enabled, automatically a new,
empty rack will be created if the current one is full. A copy of the full rack
will be stored; the data from the fractions will not be lost. This allows
changing the rack manually during the sequence without starting the
sequence again. Is this option disabled, a sequence will stop if no empty
vial is left for the next fraction.
The Empty vial check tests before the injection, if enough empty vials
for the fractions are left. Enter the number of vials needed for one run.
The software will check then before the injection, if this number of vials is
left. If not, the system will not start the next run.
Stacked Injections
Restart from first vial of current run
If stacked injections are used, check this box if you wants the collector to
start for every stacked injection with the same vial as for the previous
runs for the fraction collection. This is an option, if you inject the same
sample several times and want to collect the fractions of the same
substances from every run in the same fraction vials.
