PHOTONIS USA WAS AWARDED A PATENT FOR THE MANUFACTURE OF RESISTIVE GLASS TUBES

摘要

PHOTONIS USA was awarded a patent for the manufacture of resistive glass tubes with non-linear gradient electrical resistance changes. The patented process can be used to create a solid-piece reflectron lens for use in reflectron-type time of flight mass spectrometers. Reflectron lenses are used in Time-of-Flight (TOF) mass spectrometers to create an electrostatic field to alter ion flow, providing for a longer flight path and therefore greater resolution. Current reflectron-type TOF-MS instruments use complex multi-piece stacked ring assemblies which carry time-consuming assembly and cleaning processes.
