TWA 28

Quantitative mass Spectroscopy of Synthetic Polymers

The objective of this new TWA wss to develop mass spectrometry as a quantitative method to determine the molecular mass distribution, MMD, of synthetic polymers. The principal goals were:

  • sample preparation techniques that minimize sampling bias in terms of molecular mass
  • instrument settings that produce optimal signal-to-noise without discrimination in molecular mass distribution
  • standards for calibration of mass spectrometers
  • data analysis procedures that adequately account for factors that may distort molecular mass distributions and contribute to systematic uncertainty (Type B evaluation)
