Improved Mass Determination of Poly(ethylene glycols) by Electrospray Ion-Mobility Time-of-Flight Mass Spectrometry Coupled with Ion–Molecule Reactions
The authors developed a method to accurately measure the average molecular weight of large poly(ethylene glycols) (PEGs) using ion-mobility time-of-flight mass spectrometry coupled with gas-phase ion–molecule reactions.
