STURBRIDGE, Mass., May 29, 2015 — Photonis segmented monolithic reflectron lensesPhotonis USA Inc. offers a new segmented monolithic reflectron lens capability in its Resistive Glass line of products.

The monolithic lenses can replace traditional stacked ring reflectron lenses currently used in mass spectrometers, while simplifying the cleaning and assembly process currently required for stacked ring lenses.

Reflectron lenses are used in time-of-flight mass spectrometers to create an electrostatic field to alter ion flow, providing for a longer flight path and greater resolution. They require the use of a voltage divider in each layer to control the electric field.

A reflectron lens made with Resistive Glass provides a solid assembly replacement for a stacked ring assembly yet provides the same ability to alter ion flow, becoming a form-fit-function replacement for the multipiece stacked ring assemblies.

This new technology enables instrument designers to produce nonlinear and dynamic fields within the lens, which augments instrument performance.

The new manufacturing capability can support rings or axial lines, which can be designed for use as collision cells and ion guides.

GLOSSARY
mass spectrometry
An instrumental technique that utilizes the mass-to-charge ratio of charged particles as recorded from a mass spectrometer in order to determine the mass of a particle as well as the chemical makeup, or elemental ionic composition of a given sample or molecule.
