Intersample CF not working

Hi everybody, my goal is to calculate the next formula:
M*0,5/SC
M= Sample Area of some Specified Impurities
SC= Area of Standard substracted with blank interference 


i made 2 CF. The first is to create subtract interference from the blank in my standard(SC). It works and is the following, Peak, real, calculated , Search order result set first:
Resta_blanco_std: R.1.%(CCompRef1[Area])-B2.1.%(CCompRef1[Area])
Injection Labels,  R is my std and B2 blank ,CcompRef1 is the main peak, it works when i integrate and quantitate.

The problem is with my second CF (Calc_imp_conocidas). Real, peak, calculated, search order result set first:
M.1.%(CCompRef2[Area])*CConst1/Resta_blanco_std

M is the sample label, I put the specified impurities in CCompRef2 in the processing method, 0,5 in CConst1 but when i integrate and quantitate the injection i get an empty field. 
Could someone tell me what I'm doing wrong? Thanks.

  • Hey David,

    Do you see a result in your sample injection at the specified impurities peakvfor the Resta_blanco_std field?
    A wild guess, but i do think your Resta_blanco_std at the impurity field is not filled in because it is referenced to your Main component peak..

    Try to put your Main peak in the CCompRef1 field at the impurity you want the calculation to work for.
    Out of the top of my head. Maybe try to use formula M.1.%(CCompRef2[Area])*CConst1/R.1.%(CCompRef1[Resta_blanco_std]) and fill the main component in your impurity peak CCompRef1 in.

    Maybe that will work for you.

    I think it would be easier to use CCalRef1 for this operation instead of the CCompRef1.

    Kind regards

  • Because you are specifying the main peak as CCompRef1 in the first CF, the second CF is unable to refer back to this main peak. You could just change the first formula to:

    R.1.%(CCalRef1[Area]-B2.1.%(CCalRef1[Area]

    and then dont put in any variable in the second CF:

    M.1.%(Area)*0.5/Resta_Blanca_Std and see if you get results for your impurities. 

    If you dont want to put 0.5 in the formula, you could always create another Sample, Real CF called Factor or something similar and put 0.5 in Factor in your sample set:

    M.1.%(Area)*Factor/Resta_Blanca_Std

    Good luck. 
  • Thank you for your time and your answers, I will try :)
