Benchtop ion trap GC/MS

Varian has released the 225-MS benchtop GC/MS (gas chromatograph/mass spectrometer). The 225-MS ion trap encloses all of its components, including the foreline vacuum pump, in one compact design. Intended for use in high-throughput laboratories for applications ranging from environmental analyses to product safety, the 225-MS addresses the issue of space limitations while offering improved performance at the same time.

Mass spectrometers require two pumps to achieve sufficient vacuum: a foreline pump which is typically situated on the laboratory floor and a turbomolecular pump located inside the instrument. Without increasing the size of the mass spectrometer, the 225-MS integrates both pumps inside the benchtop unit, eliminating the floor space and hose required by an external pump.

The innovative integrated pump design offers performance benefits reducing the background signal, which allows improved sensitivity. The vacuum module does not require oil changes, eliminating the inconvenience of changing (and disposing of) the oil.

The 225-MS offers MS/MS and MS(n) capability to reduce matrix influences and provide more detailed structural information. Users can also take advantage of liquid- or gas reagent-based chemical ionisation (CI) for compound confirmation and increased selectivity. The result is enhanced qualitative and quantitative information about the sample.
