Just need a reminder on formulating custom calculation (Chemstation ver.C.01) as I haven't worked on it for years and feel something is missing from my memory. I have got several LC peaks with specific compound names, eg. A, B, C and D, and I need to build calculations arounds these peaks. Eg. to get ratios of (C+D)/(A+B) in different batches. How do I refer these specific compound peaks in a table to do the calculation?
Many thanks for anyone's help.
