Custom field to calculate peak normalization using two different injection

Hi all,

I am trying to create custom field to calculate peak normalization using two different injection.  Let say: injection 1 is the API peak and injection 2 is all the impurity peak.
I need to add all the impurity peak in injection 2 + the (API*20) in the injection 1 and multiply by 100 to get the final result, see below

Final result= ((Total impurity in injection 2) + (API * 20) in injection 1) *100

The sequence of the run is as below:

1. Assay injection
2. Related injection
3. Assay Injection
4 Related injection
5 Assay injection
6 Related injection

The calculation need to use 1 + 2, 3+4, 5+6 and so on.

    Label all assay injections A and all related injections B. Create a peak, real custom field search order Result Set Only and a formula of:
    B.%.(Total_Impurities)+((A.%.(CCalRef1(Area))*20)*100

    Make sure the All or Nothing option is set to Yes in the custom field editor and that you put your API peak into CCalRef1 of the processing method used to process your sample set. When you process and generate a result set, there will be a unique result generated in every related injection based on that particular A/B pair.

    Im not sure what you use for your total impurities in Empower so you will have to put this field into the B.%.(Total_Impurities) part, for example B.%.(total adjusted area) or whatever parameter you use for total impurities.
