Answer

With the GETSAMPLEEQUAL operator in v3.3.1 it is possible to search for a user-specified value from a column in the same column but another sample, to display the value from another column from this sample with the equal value.
Syntax: GETSAMPLEEQUAL([Results Table Column to display value];[Results Table Column to compare value])
If we use equal numeric [Sample Comments] as prerequisites for our Unknown duplicates we can set up the calculation like that:
GETSAMPLEEQUAL([Area];[Sample Comment])
And as second step for example to calculate the mean value:
([1_Get Area of equal sample comment]+[Area])/2
There is one limitation that needs to be considered: If multiple processed samples have the same input value, then the software supplies data from the first processed sample that has a match. That means for this approach, that the ‘proper’ values for further calculations are only available in the second injection of our replicates (see blue shaded rows below) – the first injection will only contain its own values.
