2025年9月17日,一场承载着高端分析仪器自主化突破使命的盛会——雪迪龙飞行时间二次离子质谱仪(TOF-SIMS)国产化项目启动仪式,在雪迪龙北京研发生产基地隆重举行。该项目的正式启动,不仅标志着雪迪龙在高端质谱仪器领域的国产化征程迈入关键阶段 ...
本研究针对锂金属负极在电池应用中面临的界面不稳定、枝晶生长等问题,通过ToF-SIMS(飞行时间二次离子质谱)溅射深度剖析技术,系统比较了Ar1500+、Cs+和Ar+等不同溅射离子对SEI(固体电解质中间相)和LiZn涂层的分析效果。研究发现500 eV Ar+能最佳解析SEI的 ...
本研究创新性地验证了飞行时间二次离子质谱(ToF-SIMS)技术在糖胺聚糖(GAGs)分析中的应用效能。该方法可在1分钟内完成样本检测,仅需75皮克样本量,通过多元变量分析(MVA)实现了不同动物源肝素(HP)的精准鉴别(灵敏度达0.001 wt%)及污染物检测,为 ...
TOF-SIMS is a mass spectrometry technique in which a solid sample is bombarded by ions, which then release fragments of the surface molecules. The material ejected from the sample typically is from ...
