How to collect spectra with modes SPECTRA ALL IN PEAK and APEX SPECTRA ONLY
Notes:
•
The peak-detection algorithm works best when a peak is reduced to 8 – 16
data points. The FLD collects the data points with an internal data rate of
74.08 Hz (= 13.50 ms) (1 signal only). The data reduction is only influenced
by the PDPWparameter.
•
The peak-detector works online on the current chromatogram. This means
that begin/apex/end of a peak is recognized with delay. Additionally the
points of spectra are sequentially acquired. This means that the acquisition
of wide range spectra lasts much longer than the acquisition of a
short-range spectrum. When you have a fast chromatography it is nearly
impossible to collect a "clean" APEX-spectra: the first/last points of the
spectra are acquired before/after you have the highest concentration in the
detector’s cell.
•
How long the acquisition of single spectra lasts is shown in the FLD’s setup
screen.
