British company Mass Spec Analytical has launched its new Thermal Extraction Ion Source (TEIS) for the Sciex 3200 Triple Quadrupole Mass Spectrometer and other V-Series models. The Mass Spec TEIS-3200 is ideal for applications where the method requires a large quantity of sample measurements in a relatively short period of time or where automation is required. When coupled with Mass Spec Analytical’s analysis software, results can be provided in as little as four seconds.

The TEIS-3200 uses Mass Spec's patented thermal extraction sample introduction device. Compounds amenable to thermal desorption, such as many pesticides, drugs and explosives, can be rapidly analyzed in this way without the need for any sample pre-treatment, solvents or glassware.

“The TEIS-3200 is easy to use, reliable, uses few or no consumables and is very fast,” explains Richard Sleeman, scientific director of Mass Spec Analytical. “The thermal system liberates samples from a large surface area, and so is ideal as a rapid screening method. Coupled with the specificity afforded by a Sciex 3200 triple quadrupole mass spectrometer, the overall system is able to provide real-time results to a forensic standard.”

The TEIS significantly speeds up workflow times by 30% or more for processes where gas chromatography-mass spectrometry (GC-MS) 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 GC columns, no special gases. An added benefit is that labs will be in the position to give virtually instantaneous results to their clients or colleagues once the analysis is complete.
