The new Thermo Scientific TSQ 9000 triple quadrupole GC-MS/MS system and Thermo Scientific ISQ 7000 single quadrupole GC-MS system offer maximum uptime, ease-of-use and sensitivity to meet increasing resource and regulatory demands. Both systems can be equipped with a new electron ionisation source designed to provide efficient ionisation of target compounds, and both systems feature the new Thermo Scientific NeverVent technology, available in the systems’ ExtractaBrite ion source configuration, which is removes the need to vent the mass spectrometer during routine maintenance operations.
