摘要:

TOF-SIMS measurements of 1 kDa polystyrene functionalized with a dimethylphenylsilane endgroup are presented and compared with measurements made by multiphoton ionization sputtered neutral mass spectrometry (MPI-SNMS). Silver cationized intact oligomer signals are obtained by TOF-SIMS and non-silver cationized intact oligomer signals are generated with MPI-SNMS. TheMnvalues from both methods are in good agreement.
