SpiralTOF™ MALDI TOF/TOF Mass Spectrometer

Revolutionary, Ultrahigh Performance TOF Ion Optics

The SpiralTOF time-of-flight optics design utilizes a figure-eight ion trajectory to allow a 17m flight path to fit in an extremely small console. This exceptionally long flight path results in an ultrahigh resolving power of >60,000 and sub-ppm mass accuracy. The versatile SpiralTOF is an essential research tool for your state-of-the-art MS analyses of functional synthetic polymers, material science and biomolecules.
