• Multiple injections, collect each run in a new group - Multiple LC runs are
collected in the same number of groups. Typically, one group refers to one
sample carrier. A group can also use multiple carriers or multiple groups can be
collected on one carrier, depending on the needs of the application.
These three options are called ‘collection presets’ and a schematically preview is
presented in the wizard (FIGURE 2-38).
FIGURE 2-38 Select the collection preset and the number of successive injections
g) Select the option that is required for your application. For this example select
the ‘Multiple injections, collect each run ...’ option and choose Next to
confirm the entry.
h) In the next step the LC parameters are specified (FIGURE 2-39). This includes
the start signal, the collection time (automatically calculated if you enter start
and end time), the LC flow rate and the delay (dead volume) between the
detector and the Probot needle. Enter the appropriate values and choose
Next .
Note: The proper setting of the delay or dead volume is especially important in
the external control mode. In the instant that a peak is detected by the detector,
the peak of interest is still in the flow cell and it takes a certain time to reach the
Probot needle (the ‘delay’ time, which defined by the tubing volume).
