Setting Up a Sequence
Sample Log Table Dialog Box
2 Set the method name by double-clicking the cell, and selecting the appropriate
method in Select File dialog box.
ChemStation uses the method to analyze the sample. Although a different method
can be used for each sample in your sequence, normally you will use the same
method for all samples in a sequence.
3 Select a sample type by clicking the cell and clicking an item in the drop-down
list.
If general.qcc is selected in ICP-MS Configuration, select one of the following six
types.
• Sample
Select this type when acquiring and processing data on an unknown sample.
• Analysis
Select this type when generating quantitative results for an unknown being ana-
lyzed by the standard addition calibration method. When a standard addition cal-
ibration method is used, all spiked samples to be used in updating the standard
addition calibration table should be set as type CalStd. The line of the sequence
controlling data acquisition of the unknown should also be set as type CalStd
with the level set at zero concentration. The sequence line following this entry
should be set as type Analysis, using the data file name used as sample. In this
way, a standard addition quantitative report can be generated for an unknown.
