ABSTRACT:

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.

Keywords: MALDI, dendrimer.
