Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) systems of magnetic field strengths from 7 to 21 T as well as Orbitrap systems were utilized to examine the complex PM chemistry, together with the development of sample preparation (extraction) protocols and understanding of the ionization characteristics for PM analysis.
