Creating a Method
3 Select elements by clicking the element push buttons in the periodic table.
The push buttons for the elements you select turn from gray to red. The isotopes for
each element are selected automatically according to the default recommended
isotopes. A convenient table with these recommended isotopes is available,
(Relative Isotopic Abundance Table).
4 Double-click on the element push button to select additional isotopes that are
not in the default method.
A dialog box for selecting isotopes will pop up. To select isotopes, simply click on
the buttons with isotope numbers and red check marks will appear next to the
number. To delete, click the right mouse button. You can select one or all isotopes
for the selected element.
Select Isotopes Dialog Box (e.g. Ge)
NOTE The pre-selected isotopes are contained in default AMU Select File (default.amu).
You can create your own AMU file to select different isotopes than default.amu. To
do so, refer to “Modifying a Method” later in this chapter.
5Click Element Information for some information about the element.
The ICP-MS DATA BASE (Element Information) window will appear. There is
more information available in this database. The name in parentheses in the title bar
indicates the type of information currently displayed, of 3 types: Element
Information, Interference Information, and AMU Information.
To view other information, select View>> Interference Information or AMU
Information.
