2.1.4 Protected chromatograms
By default, archived chromatograms are not saved indefinitely. Once the GC’s storage
capacity for archived chromatograms has been reached, the oldest archived
chromatograms are deleted to make room for the newest archived chromatograms.
If you have a chromatogram that you would like to preserve, it is possible to "protect" it.
Protected chromatograms will not be deleted to accommodate newer chromatograms. To
delete a protected chromatogram, it must first be unprotected. See
Unprotect a protected chromatogramfor more information. MON2020 will save up to 100
protected chromatograms.
Note
Protected chromatograms have a “lock” icon ( ) displayed beside them.
Note
To protect an archived chromatogram you must be logged in as a supervisor or administrator.
To protect a chromatogram, do the following:
1. Click GC Archive.
The Select Archive File(s) window appears. The chromatograms can be sorted by
date, file name, analysis type, time, or stream number by clicking the appropriate
column header. By default, they are sorted by date, with the newest chromatogram
listed first.
Note
By default, only recent chromatograms—that is, the last five runs for each stream—are
displayed. To view all archived chromatograms, click All. To return to viewing only recent
chromatograms, click Recent.
2. Make sure the Chromatogram tab is selected and then select the appropriate
archived chromatogram by clicking it. Use the SHIFT or CTRL key to make multiple
selections.
3. Click Protect.
The Edit Description window displays.
4. Enter any information that you would like to have associated with the
chromatogram and then click OK. If you do not want to enter any information, click
Cancel.
MON2020 will place a “lock” icon ( ) beside the selected chromatogram to verify
its protected status. You can also click on the Protected Chromatograms tab to view
your newly protected archived chromatogram.
