Also, further analysis and interpretation of MALDI-TOF MS spectra derived from blood-borne organisms may provide information about antibiotic resistance [23] or phenotypic traits such as the Panton–Valentine toxin in Staphylococcus aureus [24], which directly in?uence the choice of optimal...
对比市场上的产品,MASTER GC/TOF-MS做到了Z高的采集速率,可以高达30000spectra/s。并且,TOF-MS从原理上讲就容许全质量范围的快速检测:事实上从离子源得到的离子是通过连续脉冲的方式进入分析器的,其并没有进行质量选择过滤。这就避免了传统四J杆和离子阱质谱的SIM模式以及限制了扫描的频谱迁移。
实验前期采用UPLC-Q-TOF/MS技术对JPYCS全方的化学成分进行表征,总结了不同结构类型化学成分的裂解规律,以便后续的物质基础研究。大多数中药口服给药后,在体内经过吸收、分布、代谢、排泄过程,进入血液的原型成分、代谢成分或发生变化的内源性成分是中药复方发挥药效的直接物质[12]。本实验基于UPLC-Q-TOF/MS技术,...
