The ICP-MS DATABASE [AMU Information] dialog box appears, listing informa-
tion about the abundance of elements at specific masses.
ICP-MS DATABASE (AMU Information) Dialog Box
ChemStation displays the mass you selected in red.
As a default, only the element database (element.db) is loaded. You can activate
other databases containing various polyatomic species such as oxides and hydrides
by clicking the appropriate database check box at the bottom of the dialog box. You
can select multiple databases.
This dialog box also enables you access to other information. Refer to Chapter 17,
"Editing The Database" for more information about the ICP-MS DATABASE.
4 Click the element in the list for which you want to use a template overlay.
The element in the list is highlighted. A radio button is placed indicating which
mass intensity the template will be based on, called the Base AMU.
Select the element which has an isotope at the mass you selected.
5 Click Template in the Library Matching dialog box.
The template for the selected element now overlays the spectral display. The tem-
plate is displayed based on the Base AMU - a signal at the Base AMU is counted as
100% for this element.
