Hi

I am dealing with complex mixture of organic acids, in fact, these acids are extremely complex. Is there a technique in which narrow mass window extracted precursor ion can apply to separate these chemicals for the sake of qualitative analysis only. These chemicals can generate precursor ion but no or few product ions.

I searched but could not find anything. These chemicals have amu150-350. so is it possible to run the sample in multiple windows i.e. one run with 150-200 amu, and second 200-250 amu and so on

Thanks
