Peakwidth Settings
*
•
at a longer wavelength than the cut-off wavelength of the mobile phase,
•
at a wavelength where the analytes have strong absorptivity if you want
to get the lowest possible detection limit,
•
at a wavelength with moderate absorptivity if you work with high
concentrations, and
•
preferably where the spectrum is flat for better linearity.
