PDA - Photodiode Array Extension | A29 | DataApex

Product Type: DataApex

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: Isoplot, 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.

Limit values: These calculated values are compared to user-set limit values, either for each chromatogram separately or together for the selected series. Deviation of a certain parameter from the permissible limits is immediately reported and may lead to the termination of the sequence in progress.

Spectral Library: The Clarity software compares the peak spectra with the spectra of an unlimited number of spectral libraries. Spectra stored in a Spectral Library include retention times and analysis parameters (optional). The Spectral Library Search can perform automatic identification of integrated/calibrated components (peaks).

Extension for 3D data analysis from Photodiode Array Detectors.

The PDA Extension is an optional Extension 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. This extension expands the capability of Clarity by providing interactive spectral analysis, peak purity analysis and compound identification that is based on a spectral library search. PDA data can be displayed in a set of optional views including 3D rendering.

All data is saved in a single file; a chromatogram at any wavelength or even only a spectrum can simply be recalled for review after an analysis. UV-VIS spectra, acquired using a PDA detector, may be interactively selected from a chromatogram signal for visual inspection and comparison. The spectra may also be used for peak purity determinations, wavelength optimization and component identification through spectral libraries.
