Mass spectrometry Particle registration
Only charged particles are recorded in mass spectrometry. Is it possible to register uncharged radical particles using mass spectrometry? Or is another analytical method needed for this?
As far as I understood for the particals, that are produced during MASS analysis, only charge based detector can be used
@amalgama In addition to charged particles, radicals are also formed during ionization. It is clear that after ionization in the mass analyzer, the resulting ions are separated in accordance with their mass number m/z - the ratio of the ion mass to its charge, which is not typical for radicals. But is it still possible to use a detector that will register uncharged radical particles?
I haven't heard anything about such detectors
Uncharged radical particles BC· , C · , AB· are not registered. To do this, another method is needed, where it is possible that uncharged radical particles will be detected by secondary charged particles resulting from their interaction with the detector substance.
for the analysis of radicals, as it seems to me, method of electron paramagnetic resonance is most applicable
@marie-curie Thank you very much, I agree, could you recommend some literature on electronic paramagnetic resonance.
@damiryagudin maybe this one will be helpful: "Electron Paramagnetic Resonance: Elementary Theory and Practical Applications" By John A. Weil, James R. Bolton
@marie-curie Totally agree with this recommendation!
