Viewing a Tabulated Spectrum

ChemStation enables you to view results from sample analysis in tabulated as well
as graphic form. Two modes of tabulation are available for each data file you load
into the Mass Spectrum display window. The first mode provides information about
counts reported for each point per peak in the sample. The second mode provides
information about the cumulative counts of each mass measured in the sample. The
following sections explain how to view these two modes.

Performing a Points per Peak Tabulation

ChemStation provides detailed information about each point per peak in a sample.
You can view this detailed information by performing a points per peak tabulation.
Before you can perform any tabulation, you must load a data file into the Data Anal-
ysis window if one is not already showing. For information about loading the data
file, see "Loading a Data File" in this chapter.
To perform a points per peak tabulation on a data file, complete the following steps:
1 Select Data Analysis
The ICP-MS Data Analysis window appears.
>>
2 Select Data File
The Report Pad - DATA FILE NAME.TAB window appears. This window shows a
tabulated file giving information about the points per peak for the current data file.
The spectrum number, the acquisition time in seconds, and the data file name appear
at the top of the file.
