How to do weight correction in a calibration graph?


Normally the weight of the standards is entered in the sequence table in the column of compound amount (amount in Sample). The problem is that often this weight must be corrected for purity and water content, these data are variable depending on the batch of standard used.

How could we perform the calculation so that the corrected weight is the one used in the calibration graph in the report?

We are using Openlab CDS 2.3.

Thank you very much!


  • Hello,

    You can add calibration multipliers but that will only affect the results. There is no way to do calculations to affect the raw data used for the calibration regression. You would need to change the concentration of the standards in the method, sequence or injection list to change the regression and reported graph.
