Someone knows how to calculate de concentration of a impurity in relation a group of reference in EZ ChromElite? In this case, I need to discovery the concentration of a unknown impurity in relation a grupo of referency compound of cis and trans isomeres.
I tried to call this impurity as group and use the ID reference (as can see attached), but the result was 0.
Please, let me know if you need a futher information.
Thank you very much for your help and time.
