Evaluation for the surface tension of synthetic polymer using ion mobility mass spectrometry

“What determines the threshold size of cation adducted polymer in MS?” This work was started from the fundamental question. To approach for it, we performed Ion-mobility mass spectrometry (IM-MS) via electrospray ionization (ESI) and molecular dynamics (MD) simulation for evaluating spacious size and steric conformation of a cation adducted polymer. According to Rayleigh limit model, which assumes that minimum spherical polymer chain coil with excess charge, yielded very good agreement with literature-known surface tension values. The IM-MS in conjunction with MD simulation enables to solve the above question and evaluate surface tension of synthetic polymer from different type.
