Fast Atom Bombardment Ion Source Option
The GCmate and LCmate benchtop mass spectrometers can be fitted with an optional fast atom bombardment (FAB) ion source that provides a means for rapid and convenient analysis of polar or thermally labile molecules. The FAB source can be operated in positive and negative-ion mode, and it can be used for high-resolution or MS/MS measurements (with the linked scan MS/MS option). The LCmate can be fitted with an optional frit-FAB LC/MS interface, and an auto-probe has also been developed that can allow unattended analysis of up to 40 direct-probe FAB samples at a time. Some examples of FAB analysis with GCmate are shown here.
