General Purpose Agilent ChemStation Software for UV-Visible Spectroscopy — Overview
Ratio/Equation
The Ratio/Equation task is used to evaluate a user-definable equation based
on measured data and sample information. An equation can be set up using
sample data at up to six wavelengths. Weight and volume data is entered with
the samples measured. By means of an equation, for example, analysis results
based on chemical test kits can be automatically calculated and reported.
Another application for this task is to use a ratio of data values to check for
the identity or the purity of a sample.
Quantification
The Quantification task allows you to do single component analysis based on
four different types of calibration curves and a set of standards. Due to the
spectral acquisition, background corrections can also be applied to your data.
The calibration can be optimized for your concentration range of interest by
changing the wavelength used for calibration. A new calibration and a new
analysis is automatically performed, based upon your current standard data.
