5 How to optimize the detector
Set the Detector Parameters
Set the Detector Parameters
1 Set peakwidth as close as possible to the width (at half height) of a
narrow peak of interest. Refer to “Peakwidth Settings” on page 71.
2 Choose the sample wavelength
• 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.
3 Consider to use time- programming to further optimization.
