Mass Spec Applications
Sturbridge,
MA – October 24, 2003 – BURLE Electro-Optics, Inc.
announces the development and offering of its new 40mm diameter
Advanced Performance Time-of-Flight Detector. The new patented
detector’s unique small pore 5-micron MCP technology combined
with a larger collection area offers higher performance, improved
mass resolution and fast timing for TOF Mass Spectrometry.
Of special
interest to instrument designers is the detector’s large
format, 650 ps pulse width and 300 ps rise time for previously
unobtainable levels of mass resolution, dynamic range, and detection
sensitivity that is ten time that of conventional MCPs. In addition,
the detector’s flat surface provides uniform ion conversion
while the higher aspect ratio of the MCPs produce gains in excess
of 107.
The new detector is housed in BURLE’s Quick-Fit® replaceable

Breakthrough
in Red and Near-Infrared Spectral Detection with BURLE's MCP Photomultiplier
BURLE’s
new 85104 Microchannel Plate Photomultiplier (MCP-PMT) incorporates
a unique semi-transparent gallium-arsenide photocathode to provide
quantum efficiencies of greater than 20% from 370nm through 850nm
with peak efficiency of 30% at 700nm. This outstanding response
is obtained over a large 18mm diameter photocathode with a dark
count rate of less than 200 counts per second. The result is unequaled
sensitivity for applications requiring low light detection such
as chemiluminescence and bioluminescence.
By
using a dual MCP electron multiplier, the 85104 can offer a combination
of high gain, single electron resolution, fast time response and
excellent pulse linearity. Gains greater than 106 are
typical with a peak-to-valley ratio of better than 2:1. This performance
is achieved with a low dark count rate for the most demanding
photon counting applications. The single electron pulse risetime
is 750ps, with a pulse width of 2.5ns, providing high peak counting
rates approaching 100MHz and a maximum average photon-counting
rate of 5 MHz.
The
85104 MCP Photomultiplier is provided with an integral voltage
divider network for ease of use. For more demanding applications,
individual leads for biasing the cathode and MCP independently
are available to allow gated operation. This configuration is
especially useful for applications such as LIDAR and fluorescence
microscopy

BURLE
INDUSTRIES Introduces Its New 5901 MAGNUM® Electron Multiplier
BURLE
INDUSTRIES, INC announces the addition of the 5901 MAGNUM®
to BURLE’s popular compact MAGNUM®
Electron Multiplier line.
The 5901 MAGNUM®
Electron Multiplier is specifically designed for pulse counting
applications involving the detection of charged particles and
electro-magnetic radiation. BURLE’s exclusive Spiraltron™
technology uses six individual spiral multiplier channels all
fed by a single integral ion collection aperture. This increases
the linear output current and maximum count rate while promoting
longer detector life. Feedback noise is also virtually eliminated
by the high degree of channel curvature. The
detector is also available with attached leads for prototyping
applications.
The replaceable
5901 MAGNUM®
cartridge is easily installed and specially designed to be an
exact replacement for the original cartridge.

Revolutionary
Approach Developed for Electron Impact Ionization for MS Applications
BURLE
Electro-Optics, Inc. announces a revolutionary product that is
expected to change the way mass spectrometry instruments generate
gas-phase ions for their mass filters and many other applications.
BURLE’s new Electron Generator Array™ (EGA) replaces
filament-based electron sources that offer no warm-up time or
stabilization period requirement, greater control over the electron
beam’s shape and a highly uniform flux density up to 1.0
x 10-10 A/cm2.
Until now, use of conventional filament sources for producing
electrons was the long-established standard. One problem with
filaments is that they often cause pyrolytic effects, which chemically
change the unknown substance to be identified.
BURLE's patented
Electron Generator Arrays™ (EGAs), solve the problem by
producing a cold electron source that offers a rock solid electron
flux without the heat and “photon noise” typically
generated from filament ionization sources.
BURLE EGAs
exceptionally low heat output is a direct result of lowering power
consumption. A BURLE EGA producing a 50uA flux evenly distributed
over a 50mm x 8mm area, and consumes less than a half a watt.
Virtually all the current is used to produce the electron flux
with no heating of the EGA.
The BURLE
EGA consist of millions of precision glass tubes (pores) all fused
together to produce a uniform and mechanically rigid structure.
When voltage is applied across it's thickness, each pore produces
a beam of highly uniform and extremely dense electrons. The result
is an electron beam that is more uniform over a wider area than
conventional filament sources.
Applications
for BURLE EGAs include Electron Impact Ionization sources in Mass
Spectroscopy, Fluorescent display screens, electron scrub sources,
sample discharge for SEMs and more.
BURLE Electron
Generator Arrays™ can be manufactured in any shape offering
a beam shape customized to meet any application requirement. EGAs
are available in an easy to use assembly consisting of a 40mm
active area EGA Chevron™ mounted in stainless steel hardware
with mounting holes and electrical connection terminals. Custom
shapes, sizes and configurations are also available.
