Data Representation and Reprocessing

Chromeleon allows you to represent your raw data under various aspects. It depends on the aspect of interest and on the type of data reprocessing you wish to perform, which window or pane is most appropriate. For example, you can reintegrate a chromatogram manually, compare several chromatograms, analyze the peak purity, calculate calibration curves, or search single spectra in a spectra library.

Each operation appears in a separate window. Each window is intended for one specific task and has its own window arrangement and menu structure.

Immediately after data acquisition, you can perform certain steps for data reprocessing. You can define these steps in the Program in the PGM Editor; see  Post-Acquisition Steps.

You can perform all other steps of data reprocessing at any time. Use the following windows (or panes):

 The Quantification Method

 Integration

 Report Tables

 Calibration (Overview)

 The Printer Layout

 PPA: Peak Purity Analysis

 Spectra Libraries

After the raw data has been acquired, the Quantification Method determines how the data is evaluated. Thus, the QNT Editor with the Integration window is the most important window for data reprocessing.

If, after the analysis, the detection and peak table parameters chosen in the QNT Method prove to be inappropriate for the sample and/or sequence, you can change them in the QNT Editor at any time. You do not need to analyze the corresponding sample again.

All modifications are immediately and globally effective. All modified variables are immediately re-calculated and the new values are displayed on the screen. The modifications are finally accepted by selecting the Save or Save Manipulations command.

If the modified quantification method is saved, the results of all samples evaluated by this method will be adjusted.
