Reintegration new!
With software version V7.0 and later, the chroma-
tograph automatically stores the raw data of chan-
nels A and B in its main memory. The main mem-
ory in the chromatograph is large enough for 20
minutes with a data acquisition rate of 40 ms. The
raw data must be compressed if the run takes
longer than 20 minutes.
The raw data can be selected following each run in
order to reintegrate them. This is only possible if a new
run has not been started, since the raw data of the pre-
vious run are deleted when a new run is started.
It is alternatively possible to switch on continuous
transmission of the raw data so that the raw data from
all runs are stored in the control unit.
Switching the automatic raw data
transmission on or off
Select the function Reintegration in the selection dis-
play. The display File selection appears. Then press
, and move the cursor in the display Reintegration
to Transmit raw data to PC continuously. You can now
use the space key to switch between
ON
and
OFF
.
Run longer than 20 minutes?
Define compression factor
Select the function Reintegration in the selection dis-
play. The display File selection appears. Then press
, and move the cursor in the display Reintegration
to Start at or Compression. You have two possibilities:
Increasing the compression
If you increase the compression by one stage, a further
20 minutes of raw data fit into the main memory of the
chromatograph.
This compression works independent of the parameters
Peak width in the display Peak recognition. However, it
is not meaningful to evaluate raw data with a peak
width of 1 or 2 sec if they have been recorded with
compression 3. A peak width of 1 sec corresponds to
compression 1, a peak width of 4 sec corresponds to
compression 4 etc.
Shifting the start of raw data storage
If the run only takes a little longer than 20/40/60 etc.
minutes, it is possible to shift the start for saving the
raw data. This can be applied if it is not necessary to
evaluate the first minutes of the run.
