*   Searching Components
You can use the Components Editor window to search one selected subset or all the chromatographic components in the spectral or chromatographic libraries. For additional information, see Searching Chromatographic Libraries.
v
To search for a component from the processed chromatogram
1.
2.
Click the Search button, , and choose Search Selected Components.
The Spectral Tree Search dialog box opens.
3.
For details about the Spectral Tree Search parameters, see Searching Spectral Trees.
When the search is successful, the application stores the results in the Spreadsheet view in the Components Editor window.
The highest match factor for each component search appears in the Match column of the Spreadsheet view. If the search did not find any plausible hits, the match factor is not displayed.
The match factor is a number from 1 to 999 that specifies the measure of similarity between the query spectrum and the library reference spectrum. A match factor of 999 means a perfect match. Matches greater than 930 display a lightning bolt, , in the Match column.
v
To search all the components from the processed chromatogram
1.
Click the Search button, , and choose Search All Components.
The Spectral Tree Search dialog box opens.
2.
For details about the Spectral Tree Search parameters, see Searching Spectral Trees.
When the search is successful, the application stores the results in the Spreadsheet view in the Components Editor window. The spreadsheet displays the title for all hits in red.

v
To remove a component from the hit list
1.
2.
Click the Reject Library Hit button, .
v
To process the hit list of a component
1.
2.
Click the Hit Selector button, .
The Hit Selector window opens.
To distinguish the Hit Selector window from the Components Editor and Database Manager windows, the Hit Selector window has a yellow bar on the left side.
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.
