Tip!
When the
Center/Width
mode is used, a chemical formula rather than a mass can be specified for
the
Center
value. When a neutral composition is used (H
2
0, for example) a proton is automatically added
for positive mode or subtracted for negative mode (in the example the m/z of H
3
O
+
is used for positive mode).
Specify an explicit charge state by ending the composition with '+n' or '-n' where n is the charge state (if
the n is omitted, then it is assumed to be one). For example, when H
2
ONa
+
is specified the m/z of H
2
ONa
+
is used as-is.

If the active graph contains overlaid series from different samples, then the Process All Overlays? dialog opens.
9. If the Process All Overlays? dialog opens, then do one of the following:
• Select
All Overlaid
to generate overlaid XICs for all of the available samples.
• Select
Active Only
to generate XICs only from the currently active sample.
If the
