Answer

To check if unknown samples are within the calibration curve range in a SCIEX OS software results table, additional calculated columns will need to be added to the results table. To add the custom columns, open a processing method or edit an embedded processing method in an open results table then select the Calculated Columns option.



1. To enter the peak area of the largest concentration standard, type MAX([Area]) in the formula box.



2. To enter the peak area of the smallest concentration standard, type MIN([Area]) in the formula box.



3. To report the calculated concentration for the unknowns between the calibration curve range in the results table as a new column, in the Formula name column type Range Between Min and Max. Then in the Formula box type: IF(([Sample Type]='Unknown')&&([Min Std Peak Area]<[Area])&&([Area]<[Max Std Peak Area]);[Calculated Concentration];'')
