Using the Quan Reference setting

Use the Quan Reference setting on the Injections page to mark an injection as a reference.

In a given sample set, the average of all injections marked as Quan References is used for updating expected retention times and ion ratio values in the sample set.

The sample you select as a Quan Reference must be of type Standard or QC.

On the Methods > Analytes page, when you click , the retention time calculated from the average of the Quan Reference injections overwrites the expected retention times for all analytes in the group.

On the Methods > Ion ratios page, when you click , the ion ratios calculated from the average of the Quan Reference injections overwrites the expected ion ratios for all analytes.

Important: Ensure that a peak is detected in the Quan Reference injection. Otherwise, a value of 0 will be returned for the retention time and the ion ratio values will be deleted.

On the Peak Integration page, to see injections that deviate from Quan Reference, use the Injection Relative RT and Ion Ratio filters.

A Quan Reference applies at the sample group level.
