PDA Extension

Ellution Photo Diode Array Extension

The Ellution PDA Extension 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 Ellution PDA Extension expands the capability of Ellution Chromatography software 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.

The PDA Extension is an optional Extension for the Ellution Chromatography Station (starting from version 2.4) and Ellution Offline Chromatography Station. The Ellution Chromatography Station is designed to acquire and evaluate data from up to four chromatographs at a time (multi-detector measurement support). Any Instrument within the Ellution station can use the PDA Extension.

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.

A control modules for selected detectors (see list of control modules) are available. Additional control modules for other PDA detectors can be developed upon request.
