Creating a sequence
Every measurement done with an aliquot is defined by a sequence or list of elementary
process steps done one after another. These sequences are created in the sequence editor
and are stored in a library for later assignment to a concrete sample disc or aliquot.
The sequence editor is opened by clicking on a slot in the sample list. The sequence library
(Figure 15) consists of a list of all sequences created in the past. With the three buttons to
the right a new sequence can be created, an existing edited or deleted.
Figure 15: sequence library
Clicking the
new sequence
button opens the sequence editor (see Figure 16). All
elementary steps available for the specific measurement system are listed in the right list.
The list on the left side contains all steps added to the sequence in the order of processing.
Clicking on a sequence step in the
add sequence step
list opens an edit window, which will
be added to the actual sequence. In this window the single options of a step can be edited.
With the buttons at the lower border the steps could be rearranged, duplicated or deleted.
Double click on a step reopens the edit window for the according step.
With the
save sequence
button a sequence will be added to the sequence library ready to
be allocated to a sample slot.
The first and last step of a sequence normally should be a
sample charging
and
sample
discharging
step. These steps are responsible for the transport of the assigned sample disc
from the sample wheel in the measurement chamber and back. If not added, the steps in the
sequence will be processed without the sample disc on the sample arm.
Warning:
Never use a measurement sequence without sample charging and discharging!
