which displays analysis time, wavelength, and absorption
intensity. The isoabsorbance plot is especially useful to
determine wavelength maxima for complex mixtures.

Diode-array detection: 3-D data analysis
4.3.7.1 Multisignal detection
The diode-array can monitor a sample at more than one
wavelength. This is useful when the wavelength maxima of
the analytes are different. Absorption of non relevant peaks
can therefore be minimized. In addition, the quantity of
collected data can be greatly reduced if only a few wavelengths
are stored.
