PHOTONIS USA (Sturbridge, MA) has been awarded a patent for the manufacture of resistive glass tubes with non-linear gradient electrical resistance changes. The patented process creates a solid-piece reflectron lens. Reflectron lenses are used in Timeof- Flight (TOF) mass spectrometers to create an electrostatic field to alter ion flow, providing for a longer flight path and greater resolution. A reflectron lens made with resistive glass provides an assembly replacement for a stacked ring assembly yet provides the same ability to alter ion flow.
