All data is saved in a single le; a chromatogram at any wavelength
or only spectrum can simply be recalled after an analysis for review.
UV-VIS spectra, acquired using a PDA detector, may be interactive-
ly selected from a chromatogram signal for visual inspection and
comparison. The spectra may also be used for peak purity determi-
nations, wavelength optimization and component identication
through spectral libraries.
PDA View: The PDA view is customizable; up to four views can be
displayed at one time (Any combination from the following views
may be selected: lsoplot, Chromatogram, Spectra, 3D Display, Peak
Purity, Peak Purity Spectra, Library Spectra Search and Spectral
Library). The user can easily extract chromatographic signals from
PDA data to determine the optimal detection wavelength for each
peak.
PDA Method: The Clarity PDA method includes an option for
Spectral Library Search and Peak Purity analysis.
Spectral Library: The Clarity software compares the peak spectra
with the spectra of an unlimited number of spectral libraries. Spec-
tra stored in a Spectral Library include retention times and analysis
parameters (optional). The Spectral Library Search can perform
automatic identication of integrated/calibrated components
(peaks).
The library search may be constrained by the RT Window and by
Wavelength Range. Either the Least Square, the Weighted Least
square or the Correlation Method is used for calculating library
search matches. A Background Correction option is also available.
Peak Purity: This analysis helps to discover hidden impurities. Peak
Purity test is applied to all integrated/calibrated peaks in the active
signal. Purity is calculated from 5 or all spectra within the peak. The
similarity curve is displayed in the PDA window. Peak Purity analy-
sis can be optimized by setting custom preferences relating to the
purity threshold, wavelength restriction and absorbance threshold.
Import/Export Data: Spectral data can be imported/exported in
ASCII text formats to or from the Clarity software.
Reports: Users can easily include PDA options such as data 3D
Display, Isoplot, Spectra, Peak Purity and Library Search results in
reports using the intuitive Report Setup Dialog.
Instrument Control - A control module for Agilent 1100 DAD is
available. Additional control modules for other PDA detectors can
be developed upon request.
Clarity PDA Module
The Clarity PDA module is a tool that is used for processing data that has been acquired from
selected photo diode array detectors. Spectral data together with chromatograms add a third
dimension to analytical data analysis.
The Clarity PDA module expands the capability of Clarity Chromatography software providing
interactive spectral analysis, peak purity analysis and compound identication that is based on
spectral library search. PDA data can be displayed in a set of optional views including 3D
rendering.
The PDA module is optional add-on software for the Clarity Chromatography Station (from version 2.4) and Clarity EVAL.
The Clarity Chromatography Station is designed to acquire and evaluate data from up to four chromatographs at a time (multi-
detector measurement support).
Any Instrument within Clarity station can use the PDA module.
