A spectrum obtained from the average of scans, or from scans with a subtracted background, or from component deconvolution, can be further processed in Database Manager, Spectra Classifier, or can be directly searched for in a library from Chromatogram Processor. To transfer the extracted spectrum or tree to Database Manager or Spectra Classifier, use the copy button. After pressing the copy button in the Chromatogram Processor window, the mass spectrum can be pasted to a Database Manager or Spectra Classifier window. In addition, when you press the copy button in the Chromatogram Processor, the chromatogram graphic along with the spectrum from the Scan tab will be copied to Windows Clipboard and can be used for creating reports in any Windows application.

The Chromatogram Processor window contains a Search button for the direct searching of spectrum from the Scan tab or tree from the Tree pane in libraries. To search the extracted spectrum in libraries, just press the Search button in the Chromatogram Processor window and the Spectra Search dialog window will appear.

Mass Spectra obtained in Chromatogram Processor can be classified using Principal Component Analysis, Neural Networks, and Fuzzy Clustering methods.

To choose scans or deconvoluted spectra for classification:

• Select scans or components that you want to classify and click Add Selected Scans or Components to Spectra Classifier button.
