Step 4 assists the user in setting up the actual reaction run. Initial
delays and reaction phases can be added or removed and the phases itself
can be configured defining the number of measurements, instrument parameters
and all other relevant settings.
Defines the initial delay before the first reaction phase is entered.
Reaction phases define the different sections of a reaction. Each phase
may have a different duration with a different number of measurements
and measurement parameters. A simple reaction may be monitored with just
a single phase with constant measurements. More complex reactions on the
other hand may require several different phases. A phase can simply be
added by clicking on the Add Phase
button, removing a selected phase is done by clicking the Delete
Phase button. The following options are available for defining
a reaction phase:
Activating this option makes the phase an infinite phase. Only the
measurement interval must be defined additionally and the phase will run
"infinitely" until the user aborts the reaction.
A comment describing the current period may be entered for each reaction
Defines the time period between two measurements. Depending on the
selected instrument and resolution, the interval parameter may not be
freely editable. The sample measurement time rises with increasing resolution
and therefore the measurement interval may possibly be to short to perform
the next measurement on time. The software takes this into account and
suggest the minimum measurement interval for the selected instrument parameters.
Should for some reason the interval be temporarily too short between to
measurements in a reaction run, the run will not be aborted. In a case
like this the next measurement will simply be skipped and the reaction
run continues as usual. This also ensures the completion of a reaction
run even if there are temporary measurement problems.
Number of measurements:
Defines the total number of measurements for this phase.
Defines the number of scans and the instrument gain for the current
pane of the wizard shows an overview of the complete reaction. The total
reaction time and the total number of measurements for all phases are
displayed. The starting time for each separate phase is shown in the phase
