How to collect spectra with modes SPECTRA ALL IN PEAK and
APEX SPECTRA ONLY
This section describes how to overcome a malfunction in the current
implementation of the Agilent OpenLAB CDS with the Fluorescence Detector
(G7121B). In these modes spectra intermittently are not collected into the
data file.
The peak triggered spectra acquisition in the FLD is controlled by two
parameters - THRS (Threshold) and PDPW (PeakDetector PeakWidth). In
addition the parameter PKWD (Detector PeakWidth) only influences the
filtering of the chromatogram.
1 Set the parameters THRS, PDPW and PKWD accordingly to the current
chromatogram.
Best results for collecting peak triggered spectra are gathered when PDPW
is 2 steps lower than PKWD, see Table 18 on page 134.
