Testo aggiuntivo
Praise for Harald Pasch and Wolfgang Schrepp's, MALDI-TOF Mass Spectrometry of Synthetic Polymers.
JACS Book Reviews
"This book is well written and provides comprehensive information toward practical and established MALDITOF MS of synthetic polymer. Other newly developed areas, such as the analysis of nanoparticles, are only mentioned in passing, however. Nonetheless, the book is recommended reading for practitioners in this field."
