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. This innovation is a
form-fit-function replacement for the multi-piece
stacked ring assemblies, while providing the
ability to manipulate the electric field inside the
Resistive Glass products are composed of a
proprietary lead silicate glass that has been
specially processed to create an integral
semiconductive layer on the surface.
Prior studies detailing the use of a Resistive
Glass reflectron tube in an orthogonal TOF
system showed the Resistive Glass tube had
lower FWHM values, indicating a better energy
focus, while comparative spectra between a
traditional stacked ring assembly and the
Resistive Glass tube were nearly identical.

Advancing the Technology
The Resistive Glass Advantage
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 that require time consuming
assembly and cleaning processes. They also
require the use of a voltage divider in each layer
to control the electric field.
Segmented monolithic lenses made from
Resistive Glass are an alternative to traditional
stacked ring reflectron lenses currently used in
mass spectrometers. Resistive Glass tubes are
designed to guide charged particles by
generating a highly uniform electric field.
An additional patent was granted to PHOTONIS
in 2012 for the manufacture of varied, non-linear
electric fields in Resistive Glass tubes. This new
manufacturing capability enables instrument
designers to produce non-linear and dynamic
fields within the lens for better instrument
performance. Axial lines can be applied for use
as collision cells and ion guides, or rings can be
applied for use as a segmented reflectron lens.
The single piece assembly also greatly
simplifies the cleaning and assembly process
currently required for stacked ring lenses.
Resistive Glass can be easily cleaned with
water, acetone, methanol or IPA without
degrading performance, and is resistant to
scratches from light to moderate abrasions.
