    Problem with value of resolution in MassHunter Qualitative B.07.00

    wakaba.jose

      Hi

       

      I have a problem with Resolution in MassHunter Qualitative B.07.00.

       

      1) During integration program treats two peaks as one. What can I do to separate it?

           Manual integration doesn’t give any results. Please see pictures below.

       

      2) I obtain value of resolution in another sequence, but result is negative. How it is possible?? What should I change in software to obtain normal value?

       

      Regards,

      Ewa

          How your peaks are integrated is determined by what integrator you have selected in your method.

           

           

          The Agile and Agile2 integrators are parameter-less and you can only impact what they integrate by setting up peak filters. If you are using one of those, you can try switching over to either the ChemStation, General, or Universal integrators. These all have parameters that you can edit which will give you more control over how your peaks are integrated.

              Hi Ryoboyle

               

              Thank you for quick answer.

               

              I would like to come back to my previous question: what if MassHunter states, that resolution is negative value? I tried change integrator, please see pictures below.

               

              Chemstation (integrator)

              R= - 0.2 (negative value)

              Note: value disappears when I try re-integrate it manual

               

              General (integrator)

              R= - 0.2 (negative value)

              Note: the same as above

              Universal (integrator)

              Note: value disappears when I try re-integrate it manual

              Peaks are not separated, I will try to change some parameters in integrator option.

              Ewa
