MMA Analyzer
MMA – The Mini-Materials – Analyzer
The Emma (enhanced mini-materials analyser) X-Ray Diffractometer although compact in size, offers enhanced capabilities to the end user.
The original design of the MMA included such features as interchangeable parallel beam and focusing geometries, variable radius, provision for multiple detectors, interchangeable optics and many different stages.
These features are all carried over to the Emma and...
XRD Optics
Choice of Optics
Slit Optics (Standard)
The basic divergence optic is the slit optic. It includes divergence slits for 1°, 2° and 3° divergence, and the primary
beam Soller slit. The very narrow receiving slits can be fitted for special applications.
Polycapillary Optics
The optional monolithic optic “X-ray Lens” from XOS®. This monolithic optic is ideal for off-axis specimen alignment applications such as Texture...
XRD Detectors
Xe Proportional Detector Graphite Monochromator
Available in Cu or Co monochromators. (The Cu monochromator is standard with the basic Emma package.
Both monochromators utilise a special Xe proportional detector tube and low-noise preamp (linear to >90000 cps). A receiving slit, secondary Soller slit and scatter slit all work together to improve the resolution and shape of the measured peaks.
Parallel Beam or Thin...
XRD Stages
Standard Stage
The standard stage takes the standard 2 inch diameter sample holders, which are spring loaded against height setting pegs precisely adjusted to the goniometer axis
Spinning Stage
A variation on the standard stage; it holds the sample holders up against small ball-bearing rollers which are precisely adjusted to height. Spinning reduces preferred orientation effects, and is stepper motor driven.
Long Sample...
XRD Software
Automation Software
Of course no hardware control system is complete without comprehensive control and data analysis software. Operating in the Microsoft Windows® environment are two 32 bit software packages; Visual XRD and Traces.
Visual XRD provides control of hardware function of the 122E automation module and XRD system and enable the data acquisition. All scan modes and computer aided setup are...
