Abstract :
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 10 000-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.
