In this work, we report the first complete sinapinic acid clusters distribution from monomer to mega Dalton's region by matrix-assisted laser desorption/ionization (MALDI). A decrease of eight orders in intensity was observed from monomer ion to 10000-mer ion. The results fit to the model of laser ablation induced desorption process with bimodal power-law dependence. In addition, the detailed measurements on the populations of different sizes of clusters can provide some insight of different models of the mechanism for MALDI. (C) 2013 Elsevier B.V.
