New matrix, metal-phthalocyanine (MPc), of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used for analysis of small molecules (usually <500 Da). By using MPcs as matrices, small molecular samples were moved to high mass-to-charge region where there was no interference caused by the traditional matrices. The mass of the target analyte was obtained by simple calculation. (C) 2009 Shao, Xiang Xiong. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
