Answer

To add the concentrations of different isomers together when processing data in SCIEX OS Software, open a processing method in the Analytics mode of the software. Select the Calculated Columns tab in the processing method and then select Add Formula to create a custom calculation for adding the isomers. 

Type a  name for the custom calculation in the Formula Name field, and then select the GET function. For example, the custom calculation syntax shown below could be used:

=GET([Calculated Concentration];'Analyte Name 1')+GET([Calculated Concentration];'Analyte Name 2')

Make sure the analyte names exactly match the the way the name used in your results table.

Here is showing how to get value from a specific component. However, how to get value from a specific target sample? which is based on sample name not analyte name. And it would help to calculate relative percentage difference (RPD) based on the results for the parent QC spike and the QC duplicate spike. Thanks.
