JEOL Ltd. announced the release of JMS-T2000GC AccuTOF(TM) GC-Alpha, the latest model of the successful AccuTOF(TM) GC series gas chromatograph – time-of-flight mass spectrometers, to be released in February 2021. This product is a GC-MS that represents a significant improvement in performance and functionality using two newly developed Key Technologies. The basic hardware performance has been greatly improved and a new generation of automated data analysis software is included in the standard configuration. The JMS-T2000GC AccuTOF(TM) GC-Alpha, the 6th generation of the successful AccuTOF(TM) GC series, achieves three times the mass resolving power and mass measurement accuracy of the previous AccuTOF(TM) GCx-plus by using a whole new ion optics design that achieves excellent sensitivity and high data acquisition speed, the long-time hallmarks for the AccuTOF(TM) GC series. 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 ionization techniques – field ionization (FI), field desorption (FD), photoionization (PI), and chemical ionization (CI) – are optionally available, in addition to the standard electron ionization (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 ionization techniques without breaking vacuum or replacing the ion sources.
