Interpolate peak profile after scan
While scanning, the data acquisition of the detector is interrupted. This
leads to a plateau shape for that time and thus to a false quantitative
result. When this option is activated the software interpolates a
reasonable course of the chromatogram. The option is limited for runs
with a time constant ≤ 1s.
Warning! This option leads to a better shaped chromatogram;
however the quantitative results are still not fully reliable. For
accurate and reliable qualitative and quantitative results the run
should be performed twice, with and without scanning.
Scan if a peak is detected
At any detected peak the software will perform a scan automatically if this
option is activated. All further settings in this area are valid for the whole
method. You may decide whether the scan shall be performed At the
peak apex or At the beginning of the peak with the given Delay [min].
With the Slope [µAU/sec]: and at Height [µAU]: settings you can define
the thresholds, necessary for evaluating the signal as a peak. The unit
[µAU] depends on the configuration setting.
Use channel defines the data channel where the analysis is performed.
You cannot change this selection during a run. However you can change
the measuring wavelength of this channel as often as necessary.
“Scan” column in time table
If the option “Acquire 3D data” is enabled, a new column “Scan” will be
available in the time table for the detector K-2600. If you want to perform
a time-defined scan, enter a new line into the table with the desired time
and enable the scan by clicking the check box. Please note, that during a
scan the measurement signal(s) cannot be acquired. In the
chromatogram you will find a plateau for the scanning time. It is not
allowed to enable a scan in the first and last line of the time table. The
time between two scan must be 0.33 min in minimum.
