Thermo Fisher Scientific Inc. has announced the addition of negative and positive ion chemical ionization (CI) capabilities to its high-performance TSQ 8000 triple quadrupole GC-MS system.

The addition of chemical ionization to the TSQ 8000 GC-MS/MS increases analytical options available to users for addressing the challenges of complex, trace-level analysis. Chemical ionization can be used for applications such as persistent organic pollutants (POPs), and methods that use halogenated derivatized reagents.

In addition to the CI capability, Thermo also introduced direct insertion and direct exposure probe options, which further enhance the user's ability to analyze samples in the mass spectrometer. These options are useful in combination with MS/MS for applications such as the rapid structural characterization of chemical reaction products.
