powerful polymer analysis

MALDI-ToF Mass Spectrometry:

  • provides absolute mass measurements

  • does not require polymer reference materials

  • is highly accurate

  • generates fast results from extremely small sample sizes

  • is independent of polymer structure e.g. it can

          analyse rigid rods which are difficult by GPC

  • is particularly effective in ranges at masses lower

          than 4 kDa, where GPC typically falls short

  • useful for determining MMD (molecular mass distributions)       and the polydispersity of polymers
