Hello there.

I've a question regarding a parameter in Agilent MassHunter Qualitative Analysis.

I'm working on flow injection ESI-MS of methyl linoleate to study its degradation and oxidation products. When trying to understand the raw formulas, I use the Mass Calculator tool in MassHunter. However, I'm not sure about what to do with the parameter "allow both even and odd" for MS ion electron state.

I suppose that I should set it "odd", because my ions are losing an electron? Or maybe not?


Thanks for your time and patience
