白金スパッタリング法を利用した表面支援レーザー脱離イオン化の最適化とイメージング質量分析への応用
The effectiveness of platinum vapor deposition surface-assisted laser desorption/ionization (Pt-SALDI) was studied for analyses of synthetic polymers, additives, peptides, hormones, oligosaccharides and drugs. The optimized conditions of the Ar gas pressure in sputtering and the thickness of Pt film on the samples were determined. Imaging MS was performed using the Pt-SALDI.
