This is a document that introduces the Spectra module of Agilent ChemStation for LC 3D Systems software.
This manual explains how to use the Spectra Module in Agilent ChemStation for LC 3D Systems. It covers spectral analysis, library searches, and peak purity evaluation. The software supports UV-visible and fluorescence detection, allowing users to determine optimal detection wavelengths, compare spectra, and assess peak purity using spectral similarity curves and match factors.
The guide is designed for users familiar with ChemStation and chromatographic data. It includes detailed sections on spectral report styles, library search modes, background correction, and mass spectral peak purity. It also references other Agilent manuals for installation and configuration details.
Spectral analysis allows you to process spectral data acquired from the UV-visible diode-array detector or the fluorescence detector. The analysis of spectral data adds a third dimension to your analytical data when using it with chromatographic data.
One technique is to present the peak intensity (absorbance or luminescence), wavelength and time as a contour map called an isoabsorbance plot. This technique plots the spectral information as a series of isoabsorptive, concentric lines in the wavelength and time plane.
The software can perform a peak purity check, using the settings in the Purity Preferences dialog box. These qualitative results can be combined with quantitative results into a single report.
