JEOL has introduced the AccuTOF GCv|4G, which offers faster data acquisition rates and higher resolving power than its predecessor. The system has a maximum data acquisition rate of 50 spectra per second and resolving power of 8,000. The 50 Hz acquisition rate makes it possible to acquire high-resolution mass spectra in combination with third-party 2D GC. The GC-TOF system features JEOL's combination EI/FI/FD ion source, which offers both molecular weight information (field ionization and field desorption: FI and FD) and classical library-searchable (electron ionization: EI) mass spectra without changing ion sources.

With a fast analog-to-digital converter providing high linear dynamic range, the JEOL AccuTOF GCv|4G is suited to analyze complex mixtures of true unknowns, even at low concentrations.
