Jeol USA has introduced the SpiralTof Maldi-Tof mass spectrometry system for proteomics, synthetic polymers, materials and biomolecule analysis.
The SpiralTof has 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.
Jeol's technology consists of a staggered figure-eight ion trajectory of 17m.
By refocusing the ion packets during each turn, the divergence of the ions is reduced over the flight distance.
The SpiralTof ion optical system is engineered to overcome the limits of delayed extraction with kinetic energy convergence resulting in high sensitivity, resolving power and mass accuracy (less than 1ppm) over a wide mass range.
The system is available in four configurations: Maldi-TofMS with high mass revolving power and high mass accuracy; Linear Tof option for high-sensitivity analysis of high molecular weight samples and/or those that undergo post-source decay; Tof/Tof option for acquiring high-energy collision-induced dissociation (CID) product ion spectra of monoisotopically selected precursor ions; Tof/Tof plus Linear Tof for full analytical capability.
