Introduction Components Editor |
|
Components Editor allows the user to edit, search and organize chromatographic components stored in a library or generated by the Components Detection and Spectra Deconvolution feature. This module presents users with a complete set of management tools to delete unrelated components, add chemical structures, edit extensive data fields, process spectral trees, annotate spectral peaks and sort search hit lists for every component in a processed chromatogram. Components Editor is a modal window accessible from the Database Manager or Chromatogram Processor window using Edit Components  button. The modal window is a program module that pops up over an applications frame window. When the modal window is present, no other application window can be used. To close this module, click either the OK or Cancel button. If you click OK, the changes will be kept with chromatogram that can be saved into chromatographic library. You can edit associated components of a library chromatogram using Components Editor. Components Editor closely resembles visually the Database Manager module, however, the processing item is a chromatographic component rather than a database record. To ensure the modules are easy to tell apart, Components Editor has a light blue bar on the left site of the window. Both modules handle almost identically, so please refer to the Database Manager description for an explanation of module functionality. Each chromatographic component is represented by a single row. The columns contain component supplementary information. One of the columns lists Model Ion values that have been used for component detection. These values will help you quickly orient yourself and find components of interest. In most cases the model ion is the base peak in the full scan spectrum, however, if closely coeluting components have isobaric base peaks the algorithms select different model ions to distinguish the components.

Components Editor allows the user to search one selected subset or all the chromatographic components in the spectral or chromatographic libraries at once. To search selected components, select components in the Spreadsheet and click the Search  button in the tool bar and then choose the Search Selected Components item from the pop-up menu. To search all the components from the processed chromatogram, click the Search button and choose the Search All Components pop-up menu item. Note: | Searching a large number of components may take a considerable amount of time depending on the library size. |
After the search is completed, the highest match factor for each component search is listed in the Match column in Spreadsheet. If the search procedure did not lead to any plausible hits, the match factor will not be displayed. If at least one hit was found, the text in the name filed of the component row will appear in red. To process the hit list of a component, select the component row and open the Hit Selector window by clicking on the Hit Selector button  . In Hit Selector you can review the hit list and accept a library record that correspond to the component by selecting the hit and clicking OK button. If you accept a library record for a component, all relevant information (structure, name, mol. mass, ion types etc.) will be adopted and entered in the component fields. If you decide to reject the hit list, click Cancel. You can undo an accepted hit by clicking the Reject Library Hit  that is displayed next to the Hit Selector button. To ensure the windows are easy to tell apart, Hit Selector has a yellow bar on the left site of the window. Note: | The Hit Selector window lists the best matches found during the library search. The match factor describes the similarity of the match to your component. |
