Determination of end groups of synthetic polymers by matrix-assisted laser desorption/ionization: High-energy collision-induced dissociation
UNSPECIFIED. (1999) Determination of end groups of synthetic polymers by matrix-assisted laser desorption/ionization: High-energy collision-induced dissociation. ANALYTICAL CHEMISTRY, 71 (17). pp. 3637-3641. ISSN 0003-2700Full text not available from this repository.
Matrix-assisted laser desorption/ionization has been combined with high-energy collision-induced dissociation for the analysis of poly(ethylene glycols) with butanoyl, benzoyl and acetyl end groups, using novel technology comprising a magnetic-sector mass spectrometer and ion buncher with an in-line quadratic-field ion mirror. High-energy (> 8 keV) collision-induced dissociation facilitated unambiguous end-group determination of these polymers, providing masses of end groups and structural information. The high-energy collision-induced dissociation also provided information regarding repeat units.
