peak of interest.
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.
