Description

Single piece reflectron lens simplifies cleaning

A reflectron lens made with Resistive Glass provides a solid single-piece assembly replacement for a stacked ring assembly while still providing the ability to control or alter ion flow. Photonis’ patented Resistive Glass technology gives our reflectron lens the ability to produce excellent linearity and improve overall instrument performance. Because of their simplified design, Photonis’ reflectron lenses are easier to clean and maintain, therefore offering significant improvement over traditional assemblies.

Photonis designed the reflectron lens to be a significant improvement over the stacked ring assemblies used in Time of Flight Mass Spectrometry. In a direct comparison, the Resistive Glass reflectron provided equal or better performance in an orthogonal TOF system than a traditional stacked ring reflectron, as demonstrated in Figure.
