Effect of high mass accuracy on the analysis result by JMS-T2000GC−Effect to narrow down the result of msFineAnalysis integrated analysis
MSTips No. 331
JEOL Ltd. recently announced the JMS-T2000GC "AccuTOF™ GC-Alpha" which is the 6th generation GC high resolution time-of-flight MS (GC-HRTOFMS) in the "AccuTOF™ GC" series that was first released in 2004. The GC-Alpha (Fig. 1) represents a significant improvement in capabilities over the previous model with three times higher mass resolving power (10,000→30,000 @ m/z 614)and three times higher mass accuracy (3ppm→1ppm, EI standard ion source). In this work, we used the thermal decomposition of an acrylic resin to evaluate how improved mass accuracy can affect the analysis results for a complex sample. Additionally, the msFineAnalysis Version 3 software included with the JMS-T2000GC was used to quickly determine the impact of improved mass accuracy on the qualitative analysis results.
