JEOL JMS-T2000GC AccuTOF GC-Alpha GC-MS

JEOL has released the JMS-T2000GC AccuTOF GC-Alpha, the latest model in the AccuTOF GC series gas chromatograph–time-of-flight mass spectrometers. The product is said to represent a significant improvement in performance and functionality, as the basic hardware performance has been improved and next-generation automated data analysis software is included in the standard configuration.

The product achieves three times the mass resolving power and mass measurement accuracy of the previous AccuTOF GCx-plus, by using an ion optics design that achieves high sensitivity and data acquisition speed. Additionally, the system has a wide dynamic range that is beneficial not only for quantitative analysis but also for qualitative analysis of complex mixtures.

A wide variety of ionisation techniques — field ionisation (FI), field desorption (FD), photoionisation (PI) and chemical ionisation (CI) — are optionally available, in addition to the standard electron ionisation (EI). Two combination ion sources are also available as options — the EI/FI/FD combination ion source and the EI/PI combination ion source, which allow easy switching between ionisation techniques without breaking vacuum or replacing the ion sources.

The msFineAnalysis automated data analysis software provides qualitative results by combining data acquired by EI and soft ionisation (FI, CI, or PI) in a simple, speedy and automated way. The software makes full use of the high-quality data obtained by the GC-MS, thus enabling qualitative analysis for identification of unknown compounds.

The two-sample comparison function provides volcano plots, which can visually illustrate the distinguishing components between the two samples. After determining whether there are differences, integrated analysis is performed for all components. The software also supports analysis of GC/EI data alone.
