TOFMS系统主要特点 飞行时间质谱(TOFMS)具有很高的采集频率,极大地增强了 GC×GC的定性能力。为复杂样品分离分析提供更有效的解决方案。TOFMS理论上对测定对象没有质量范围的限制,具有极快的响应速度及较高的灵敏度。TOFMS高样品通量,稳定性好。TOFMS的高速全部采集(500张全谱图/秒)可以快速完整定义很窄的峰并且...
GC-TOF/MS analysis An aliquot of 1 μL of each derivatized sample was injected in a splitless mode by autosampler Combi-PAL Agilent (Waldbronn, Germany) into an Agilent 7890 gas chromatograph coupled to a Pegasus II time-of-flight (TOF) mass spectrometer (Leco Corp., St. Joseph, MI, US...

The aim of this article is to give a description of the GC-MS methods for lower plant glycolipid fatty acids. Although the text deals mainly with examples of algae and mosses, it should be kept in mind that the methods presented are frequently also suitable for higher plants. However, when...
The acquired MS data from GC-MS were analyzed using the Chroma TOF software (v 4.34, LECO, St Joseph, MI). Metabolites were analyzed qualitatively using the NIST and Fiehn databases, which were linked to the Chroma TOF software. Briefly, after alignment with the Statistic Compare component, ...
