Changes in the Homogeneity of Poly(Arylester) Dendrimers during the Matrix-Assisted Laser Desorption/Ionisation Mass Spectrometry Experiment

The loss of homogeneity of poly(arylester) dendrimers during the matrix-assisted laser desorption/ionisation experiment is discussed. Both laser-induced fragmentation and reactions in solution before sample deposition may lead to spectra of polydisperse materials.
