Adding Compounds to the Library
If you need to add compounds to your library, you need to run an analysis of the
compounds and then add each compound to the library. Although you can add
compounds to
Explorer directly using the following procedure, we recommend
using SiteChart to create and modify library information. If you have prepared a
library on the instrument there is no way to save it. It will be lost when another
method is loaded. If the library is created in SiteChart you can save it as part of a
custom method for later use. It can then be downloaded to
Explorer at any time.
1. Refer to the user notes supplied with your assay to determine which columns
will provide the best separation for your compounds. You may require two or
possibly all three columns. If your method requires two or more columns you
must repeat this procedure for each column.
2. Select one column/detector combination and disable the other two columns.
3. Press Enter Menu, then LIBRARY.
The library for the selected column will be displayed.
4. Delete any compounds that are not required for your assay.
5. Press LIST, EDIT, STORE, EDIT. You will be prompted for a Peak No. Enter
0 to delete the peak from the library.
6. Press DISPLAY, GC, GRAPH.
This will display the chromatogram so you can see the compound peaks. You
can also use the peak report display.
7. Connect a sample to the sample in port and begin a run.
If you are performing a syringe injection, prepare the syringe sample and inject
it at the beep. You may have to do a few runs in order to optimize your method.
Once you have obtained well separated peaks at the desired analysis time then
you can store the compounds in the library.
8. When the analysis is complete, press LIBRARY, LIST, EDIT, STORE.
