Field desorption mass spectra often contain few peaks, the largest of which are [MI: and [M+H]' ions. Because of this lack of fragmentation accurate mass measurement is of primary concern in field desorption mass spectrometry. Although total ion yield per quantity of sample may rival electron impact

A selection of hydroxyacetophenones has been investigated as matrices for the analysis, by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), of high molecular weight (HMW) glutenin mixtures from three wheat varieties. Mass spectra were obtained directly from the HMW glutenin

The measurement and recording of peak signals at high mass is often ditlicult and susceptible to a large degree of error. Signal averaging of repetitive scans has been used to improve detection limits and aid nominal mass assignment by peak matching. This is illustrated using glucagon as the referen

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

## Abstract We have developed surface‐assisted laser desorption/ionization mass spectrometry using zinc oxide (ZnO) nanoparticles with anisotropic shapes (ZnO‐SALDI‐MS). 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
