• Signals
: Up to eight separate signals (chromatograms) can be recorded. To
mark a signal for collection the
Use Signal
box is checked for that signal, the
wavelength and bandwidth are defined, and if a reference signal is required
that box is checked and defined.
•
Wavelength
sets the central wavelength (nm) of the signal,
•
Bandwidth
sets the width (nm) of the signal,
•
Reference Wavelength
sets the central wavelength (nm) of the reference
band which is subtracted from the analytical signal,
•
Reference Bandwidth
sets the width (nm) of the reference band.
• Peakwidth
sets the data collection rate and signal filtering.
• Stop Time

and these values are usually
taken care of in the

tab. However, the detector module Stop Time can
sometimes differ from the pump Stop Time when it is required that data
