1 Introduction to Your System
General Purpose Agilent ChemStation Software for UV-visible Spectroscopy — Overview
Fixed Wavelength
The Fixed Wavelength task is used to look at measured sample data at up to
six different wavelength. This data is available as absorbance, transmittance
and first to fourth derivative.
Due to the spectral acquisition additional techniques such as internal
reference or three-point, drop-line background corrections can be applied.
Spectrum/Peaks
In the Spectrum/Peaks task you are looking at absorbance minima and
maxima. The focus here is more on the wavelength scale but you get the
according absorbance readings in addition.
