Setting the new standard in MALDI-TOFMS performance
To improve the mass resolving power and mass accuracy of a time-of-flight mass spectrometer, the flight distance must be extended while keeping a group of ions having the same m/z (an ion packet) from diverging in space.
The innovative SpiralTOF ion optics was developed by JEOL based on the "Perfect focusing" and "Multi-turn" principles. The ion packets are focused back in space at every fixed distance (i.e., each figure-eight trajectory) during the flight. Thus, even after the extended flight distance, the ion packets do not diverge at the detection plane, achieving high mass resolving power, high mass accuracy, and high ion transmission.
Reduced topographic effect of matrix crystal
The topographic effect of the matrix crystal leads to a difference in flight start position for the ions, resulting in a difference in flight time. In the conventional ion optical system, this time difference degrades the mass resolving power and also the mass accuracy obtained with external mass calibration. With its extended flight distance, the JMS-S3000 reduces this effect to the minimum and achieves highly reproducible mass resolving power
