Empty entries in Constant file

Hi everyone

I’m working with OpenLab CDS v2.7 to create report templates.

In these programs, I’m trying to create a report template for an analysis of known and unknown impurities, which also uses as Constat file for several parameters.

Example of one of my Constant Files::

I want to create a CustomCalculation, which can determinate, whether the compound is a known impurity or an unknown impurity and use for all unknown impurities a response factor of 0.98.

Compound        Retention time                 Response factor

Compound_A  2.45       1

Compound_B  3.69       1

Known imp.A   3.38       1.2

Known imp.B   5.64       0.8

I want to create a CustomCalculation, which can determinate, whether the compound is a known impurity or an unknown impurity and use for all unknown impurities a response factor of 0.98.

Was this helpful?
