New High-Resolution Stable Mass TOF Spectrometer

Zoex Corporation recently announced the FasTOF, a high resolution TOF mass spectrometer, specifically designed for comprehensive two-dimensional gas chromatography applications.

The FasTOF is sold as a system bundle including the Agilent 7890 GC, the Zoex thermal modulator, and the Zoex HiResTOFMS module. FasTOF is equipped with a unique, patent pending mass calibration system.

Calibrant material is pulsed into the ion source in synchrony with the GC x GC modulation cycle. This permits the mass scale to be fully recalibrated every few seconds throughout an analytical run, with no

interferences between the calibrant material and analyte ions. The result is the most stable and accurate mass measurements: +/- 0.0007 Th (1 Thompson is approximately 1 amu) of any instrument in its class.

Elemental composition assignments are routine with this instrument, which is targeted at complex mixture analyses in metabolomics, environmental forensics, flavors/fragrances, petroleum liquids, and other demanding applications.
