Setting Isotope Ratio Parameters

To generate a report for isotope ratio analysis, you must first set the parameters from
the ICP-MS Data Analysis window. Setting isotope ratio parameters includes setting
mass bias correction, selecting the element, and specifying the isotope ratio.
To set the isotope ratio parameters, complete the following steps:
>>
1 Select Top Data Analysis.
The ICP-MS Data Analysis window appears.
Load a data file by selecting Data File >> Load in the ICP-MS Data Analysis win-
dow.
Selecting Data File>>Next Data File will load the data file that alphabetically fol-
lows the current data file in the same directory. For example, if the directory con-
tains the following files:
Soil01.d
Soil02.d
Soil03.d
Water01.d
Water02.d
Water03.d
and soil03.d is currently displayed, selecting Next Data File will load water01.d. If
the current data file is the last one in the directory (in this example water03.d) the
message No Next File is displayed. To initiate this feature, the user must have first
selected a data file from the Load Data File dialog box (from the Data File menu in
Data Analysis).
This menu item is not related to the numbered items near the bottom of the menu,
which display the most recently loaded data files.
The three most recently loaded data files are listed as numbered menu items, with
the first entry corresponding to the most recently loaded data file. Selecting any one
of these numbered menu items will cause that file to be loaded into data analysis.

Data Analysis icon.
