## Abstract We have developed surfaceβassisted laser desorption/ionization mass spectrometry using zinc oxide (ZnO) nanoparticles with anisotropic shapes (ZnOβSALDIβMS). The mass spectra showed low background noises in the low __m__/__z__, i.e. less than 500 u region. Thus, we succeeded in SALDI io
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is shown to give inaccurate results for the analysis of low molecular weight ethoxylate polymers. It is demonstrated that when the degree of ethoxylation is low (n < 9), MALDI-TOFMS produces substantially high
