In this study we applied ion mobility mass spectroscopy(IM-MS), which enables to measure molecular weight and spacious size simultaneously, to classify isobaric star-polymers originally synthesized polyethylene glycol with multi-arm. Experimentally, spacious size is quantitatively observable as a collision cross section (CCS) which corresponds to average projected area of sample ion. CCS was theoretically evaluated using structure via molecular-dynamics simulation. Comparing experimentally and theoretically obtained CCS, we speculated conformation and dimension of polymer ion quantitatively.
IM-MS simultaneously provides molecular weight and spacious size of synthetic polymer, which is a crucial method for classifying star-polymer.
