A manufacturer of various analytical
instruments for the pharmaceutical industry, among other markets, Madison,
WI-based Bruker AXS recently evaluated the gear sets used in the design of its
D8 Series of analytical diffractometers.
After
testing the existing gears used by Bruker, the company decided to start using
brass worm gear assemblies provided by Forest City Gear (FCG). The gears are
used to position certain optics and shutters on the diffractometers. These
systems are typically found in research labs and R&D facilities at academic
institutions as well as industrial locations.

The
analytical diffractometers manufactured by Bruker AXS address a range of
applications, including phase identification, phase quantification, texture,
stress, single crystal diffraction, small angle X-Ray scattering,
high-throughput screening, microdiffraction, reciprocal space mapping,
non-ambient characterization, high-resolution X-Ray diffraction, reflectometry,
gracing incidence diffraction, indexing and structure solution.
Because of
the variety of end uses for these diffractometers, they have to be able to
handle the smallest and largest samples and sample amounts, inhomogeneous
samples, as well as those of complex shape geometry and samples of heavy
weight.
Some of the
key components on the D8 series of diffractometers include the patented Bruker
automated laser-video alignment system and the patented Hi-Star area detector.
The combination of these two components enables precision alignment of sample
features for instant analysis in snapshot or movie mode. The peak to background
ratio of the data collected is close to the theoretical limits, owing to the
sensitivity of the Hi-Star detector. The worm gear sets, now provided by FCG,
are used on these systems for the precise alignment and positioning of the
incident beam. The proper alignment of a system starts with the incident beam,
so the gear movements must be extremely accurate and highly repeatable.
The D8 Apex
II series of instruments from Bruker AXS is another system where the FCG gears
are used. The APEX II line of chemical crystallography solutions are designed
for single crystal structure determination. These instruments are recognized
for their ease of use, state-of-the-art software and for having the fastest, most
sensitive low-noise APEX II detector. These features, combined with the precise
and flexible goniostats, provide the best data possible, quickly and reliably,
to the academic lab or industrial research facility.
