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)
