MALDI-TOF System JEOL's MALDI-TOF mass spectrometer, the JMS-S3000 SpiralTOF, reinvents Time-of-Flight ion optics with an extended flight length in a compact footprint, delivering a resolving power of greater than 60,000 (FWHM) over a mass range of m/z 10-30,000.
Proprietary technology consists of a staggered figure-8 ion trajectory of 17 m. By refocusing the ion packets during each turn, the divergence of the ions is reduced over the flight distance. The SpiralTOF ion optical system overcomes the limits of delayed extraction with kinetic energy convergence, resulting in high sensitivity, resolving power and mass accuracy (<1 ppm) over a wide mass range.
The system is available in four configurations: MALDI-TOFMS with high mass resolving power and accuracy; the Linear TOF option for high sensitivity analysis of high molecular weight samples or those that undergo post-source decay; the TOF/TOF option for acquiring high-energy collision-induced dissociation (CID) product ion spectra of monoisotopically selected precursor ions; and TOF/TOF plus Linear TOF for full analytical capability.
