Purity CF

Hi, 
I would like to create the calculations for a purity method. 
In the standard solution there are 2 impurities and the main component, each with a different concentration. 

The preparation of the standard solution is:
Sol A:  62.5 mg IMP 1 diluted in 25ml. 2,5ml of this solution diluted in 50ml
Sol B: 25mg IMP 2 diluted in 25ml. 2,5ml of this solution diluted in 50ml
Standard Solution: 50mg main component + 1ml Sol A + 2,5 ml Sol B diluted in 25ml 

So I have imp1 dilution 1/12500, imp2 dilution 1/5000 and main component dilution 1/25

Imp1 and Imp2 in the sample are calculated as follows:

C=Concentration Imp (1 or 2) in the Standard Solution
V=Volume of the Sample Solution (50ml) 
W=Weight of the Sample in the Sample Solution
ru=Area imp (1 or 2) in the Sample Solution
rs=Area imp (1 or 2) in the Standard Solution)

I know that I can put the concentration of the three components in the value tab, but I would like to create a CF that contains the dilution so I can insert only the components weights in the value tab.

Is it possible? Thank you in advance

    Hey Zonghi,

    You could set the dilution of the components in the CConst* fields in your processing method and create a custom peak field incorporating the CConst*.

    I think that is the most easiest approach.
