ABSTRACT
The introduction of Matrix-Assisted Laser Desorption/Ionization (MALDI) 1–5 and Electrospray Ionization (ESI) 6,7 (Chapter 1) has dramatically increased the mass range for molar mass analyses by mass spectrometry. In principle, both techniques are able to produce intact quasi-molecular ions of polymers with high molar mass (>100,000 Da).
