Compound math in quant analysis B07.00

mauricio Jun 18, 2018 7:39 PM

Hi, I need to calculate total xylene from p Xylene, m Xylene and or Xylene.
I have Masshunter Quant Analysis B07.00 Build 7.0.457.0
In the options of the quantifier table I only have the option Cmpd. Group and I can not select Compound math since it does not exist in the drop-down list.

Can this be done with this version?

Thank you

Hello,

I added tags to this post to increase visibility.

Just to verify that I am understanding your problem description, are you saying that there is no Compound Math column available to add when you are in the Compound Setup section of the Method Edit view?

  Yes, it does not appear in the available columns.

    Sorry for the delay. The compound math column was not introduced until rev B.07.01. Probably the best thing for you to do would be to upgrade to a more recent revision of the software so that you can take advantage of the workflow outlined in this video: How to summate peaks in MassHunter Quant B.08.00
    
    If you are unable to upgrade, then this document walks through an alternative, more involved workflow: Instructions for Enabling Compound Math on B.03.0x-B.07.00
    
    Please let me know if you have any questions.

      Thank you very much for the information.
      I'll try the second alternative for the moment

        Just following-up. Did that recommendation work for you? Let us know if you need any further help.

        Sorry for the delay.
        With respect to the instructions to enable the compound math, I have the following questions:
        Item 4) Save the file
        If I have compound 1, compound 2; and compound 1 + compound 2. Why is compound 1 / compound 2 added?
        In Custom Calc I obtained a zero value and the responses of both compounds were not added.
        
        Something I'm doing wrong?

  Hello,
  
  Sorry for the delay.
  
  I initially thought that maybe the spaces in your compound names were causing an issue, but I was not able to reproduce this issue. Is it possible that you did not copy another compound's calibration levels to the new "Math Compounds" when you added them to the method?
