Varian has introduced what it terms as the first true benchtop ion trap GCMS system. The 225-MS ion trap is the world's first mass spectrometer to enclose 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 important performance and ownership benefits:
* It reduces 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 ionization (CI) for compound confirmation and increased selectivity. The result is enhanced qualitative and quantitative information about the sample.
"Combining Varian's expertise in vacuum technologies and mass spectrometry, the 225-MS delivers a compact solution without compromising performance," said Martin O'Donoghue, SVP Scientific Instruments. "In fact, the innovative design increases the sensitivity of the instrument."
