The latest evolution of Mass Spec Thermal Ion Source makes the same technology that enabled Mass Spec to amass some of the largest forensic chemistry databases in the world available to all Sciex API 3200™Triple Quad users.
It is ideal for applications where the method requires large quantities of sample measurements in a relatively short period of time or where automation is required. The key benefit of the approach is the lack of sample preparation needed – meaning that a wide variety of methods can be accommodated.

Compatible with the Sciex API 3200™Triple Quad System
The TEIS-3200 uses Mass Spec's patented Thermal Extraction sample introduction device: two heated nickel coated brass plates with a cavity between them. Ambient air is continuously drawn into this space and through a ceramic transfer line into the Atmospheric Pressure Chemical Ionisation (APCI) ion source.
Compounds amenable to thermal desorption, such as many pesticides, drugs and explosives, can be rapidly analysed in this way without the need for any sample pre-treatment, solvents or glassware. The approach of directly analysing materials by thermal desorption tandem mass spectrometry (TD-MSMS) has been successfully applied to the forensic analysis of drugs of abuse, the detection of explosives, and with reference to an increasing database of MS/MS spectra, could help to identify an expanding suite of compounds.
The Thermal Extraction Ion Source significantly speeds up workflow times by 30% or more for processes where GCMS is normally used for analysis. Much of the time saved is in the sample queue for analysis, which may be overnight, but there are other savings: no solvents, no glassware, no labelling of vials, no loading up the auto-sampler, no reconciling the queue with the sample list, no reconciling the results to the correct vial in the correct position, no GC columns, no special gases. An added benefit is that the lab would be in a position to give virtually instantaneous results to their clients or colleagues once the analysis is complete.
