This SpiralTOF™ is a special MALDI-Time-of-Flight mass spectrometer. Its patented spiral ion optics provides a 17 m flight path in a very compact format. Therefore, the SpiralTOF™ sets new standards for performance and mass resolution. It is a must-have instrument for demanding analytical tasks in all fields of natural science research, such as biochemistry, material science, and polymer research.
The SpiralTOF™ is available in two different configurations. The standard MALDI-TOF MS comes with an additional linear TOF unit. It can optionally be combined with a TOF-TOF unit. This way you get exactly the right instrument to meet your requirements.
The unique ion optics of the SpiralTOF™, which was developed by JEOL, allows flight distances of 17 m. For this application, the ions circulate up to 8 times in the spiral design. During this operation, the ion packages are refocused during each circulation. This ensures a resolution above 75,000 (FWHM) over a very large mass range, even for extremely long flight paths.
