    OpenLab CDS Chemstation - Standard curve generation from a sum of multiple peaks



      I had to convert from Empower to Chemstation and finding it quite difficult.


      I am trying to set up a calibration method for my compound which elutes as three separate peaks (different isoforms). I am using a 6-point standard curve with the reference standard. I defined three peaks as a separate compounds and grouped them together defining a total amount in the sample for each level. What I get is a separate standard curve for each compound.

      How can I add all the peaks to generate a standard curve for a total amount (consisting of three peaks)?

      Also, in the reporting I would like to still see what is the percentage of each of the compounds for the assessment of the quality of my product.

      I would be really  thankful for any hints.


      Many thanks,
