Introduction of the
X’Celerator detector, the
world’s first solid state
1D detector
The world’s first
commercially
available X-ray
diffractometer
The X-ray source, the goniometer, the
sample stages and the detection system
are all brand-new. Such innovation
comes to the market just once in a generation and sets the benchmark for others to follow. Empyrean not only meets
the high expectations of scientists and
XRD experts today, but will continue to
do so as research themes evolve. The
world of materials science is constantly
changing and the life of a high performance diffractometer is much longer
than the typical horizon of any research
project. With Empyrean, you are ready
for anything the future holds.
What’s in a name?
The term Empyrean is derived
from Aristotelian cosmology (384
-322 B.C.) in which spherical earth
was surrounded by concentric
celestial spheres containing the
moon and known planets1. The
highest sphere, later referred to as
Empyrean in the Middle Ages, is
represented by the element ‘fire’.
The Empyrean XRD system is the
product of the fire of innovation,
and is truly above all others,
capable of the most analytical
applications on a single XRD
platform.

EMPYREAN
Powders – data that speaks for itself
Full pattern quantification
Rietveld standardless quantitative
analysis has become an important
method for characterizing complex
mixtures.
Empyrean offers you a
platform to measure and
identify the most complex
phase mixtures. The
sensitivity of the instrument
and the power of the
software to deal with
overlapping patterns is
unmatched.
Empyrean has the highest
angular resolution of
any laboratory powder
diffractometer and delivers
data closest to synchrotron
quality.
Empyrean offers the widest
range of non-ambient
environments, under full
control of the instrument
software.
Empyrean is ideal for
teaching purposes. It offers
all relevant diffraction
geometries (reflection,
transmission, capillary, microdiffraction, Debye-Scherrer)
and is supported by the most
comprehensive set of worked
examples.

Every Empyrean equipped with a PIXcel3D detector is
capable of 2D diffraction. 2D diffraction patterns show
if a sample is fine-grained enough to produce the solid
Debye rings characteristic of a randomly oriented sample
(a), or is medium to coarse-grained, producing spotty
Debye rings (b and c).

Low-angle diffraction from dry rat tail tendon collagen fibers
as a function of their orientation.
When the fiber axis is oriented perpendicular to the incident
beam (dark blue line) equidistant meridional reflections due
to the characteristic collagen molecule arrangement along
the fiber axis can be clearly observed. The data shown in the
insert was taken by using a hybrid monochromator for best
low-angle resolution. The first diffraction peak, corresponding
to a Bragg spacing of 650 Å, is readily resolved. When the
fiber is oriented in parallel to the incident beam (equatorial
orientation), no such peaks are observed (light blue line).

NbAl thin film multilayers grown
on sapphire and silicon substrates
show fiber texture. Reflectivity
and wide angle scanning provide
information in just 5 minutes.
Reflectivity gives data about
multilayer thickness and interface
roughness. Wide angle scanning can
be supported with texture studies
using pole figures and or 2theta/
omega scans at different omega
offsets. Note that the Nb(121)
reflection, for example, is absent
from the symmetric scan but can be
observed with omega offset of 30°.
A pole figure shows the Nb(121)
reflection as a ring also illustrating
that the film orientation is

Nanomaterials – data that speaks for itself
Pair distribution function (PDF) analysis
Qmax=21Å-1 (Ag)
For the analysis of nanoparticle size,
shape, specific surface area or dilute
dispersions, EasySAXS, PANalytical’s
small angle X-ray scattering (SAXS)
application, is designed for ease of use.
The size of crystalline domains within
nanomaterials can be obtained from the
line profile analysis within HighScore
(Plus). Structure analysis of amorphous
or nano-crystalline materials can be
undertaken with pair distribution
function (PDF) analysis.
The large range of non-ambient
environments available for the
Empyrean can also be used beneficially
for synthesizing and characterizing
nano-materials. For example, the
sintering of nano-particles as a function
of temperature, be it in air, vacuum or
other gasses, can be observed. Catalytic
activity, under gas pressures up to
100 bar, can be studied. For all these
applications Empyrean allows users to
pick and place the right PreFIX X-ray
components to give the best results.

PDF analysis is preferably performed with high-energy radiation. Every
Empyrean supports the use of Mo or even Ag radiation, with slit optics
or dedicated mirror optics. The graphs show that the use of longerwavelength radiation significantly reduces the quality of the experimental
PDF. Results obtained with Ag radiation on Empyrean compare very well
with beam line experiments.

Information on the microstructure of crystalline materials (crystallite size and microstrain; also known
as size-strain analysis) is obtained from the width and the shape of X-ray diffraction peak profiles.
HighScore (Plus) can calculate size and strain information for each diffraction peak.
The screen shot also shows the Williamson-Hall plot giving the average size and strain results.

EMPYREAN
Empyrean can handle all of these
samples.
For the phase identification of rough
and irregularly shaped objects,
parallel beam geometry is often used.
PANalytical’s philosophy for this
geometry is consistent with all our setups - optimize, not compromise.
Empyrean can also analyze large and
heavy samples up to 10 kg, a unique
capability for a flexible multi-purpose
X-ray system. The 3-axes Empyrean
cradle allows you to mount components
of up to 2 kg, and perform preferred
orientation (texture) and residual stress
using the chi-tilt or omega-tilt method.
A further unique possibility with
Empyrean is to see inside small solid
objects without having to cut them.
Computed tomography (CT) analysis
determines the area of interest for
subsequent X-ray diffraction analysis, or
can be used to check for the presence of
pores.
CT can be used to visualize the
fabric, defects and inclusions
of a sample. The density of the
sample can be obtained and
differences can be calculated.
This provides a valuable new
tool for researchers and gives
new possibilities for the interpretation
of the XRD data. Especially the
combination from 1D and 2D diffraction
information with 3D–CT supplies the
first time a complete picture of the
sample.
In this example two concrete samples with different properties are shown. The X-ray patterns
on the right show a clear presence of Portlandite and a reduced amount of calcite in the upper
sample (prepared with glass). The other sample shows a significantly lower amount of Portlandite
and an increased amount of calcite (sample prepared without glass). This can be explained by
the microstructure that is visualized by CT: The upper sample shows a more dense microstructure
inhibiting carbonatization whereas the other sample shows more pores and cracks that allow for a
stronger carbonatization – affecting the long term stability.

Radiography, computed tomography and microdiffraction
Empyrean offers unrivalled possibilities
for non-destructive analysis on natural
or historical objects.
As example we analyzed a river shell
combining CT and XRD data:
The radiograph on the right side
exhibits some voids in the shell that
are not visible from the outside. The
CT reconstruction of the shell (middle)
allows in addition slicing the shell in
planes and analyzing the structure
in more detail. At the position of the
arrow (connection of the shell muscle) –
also marked in the picture by the green
spot - an analysis of the aragonite phase
orientation has been performed:
The strong preferred orientation of
the aragonite is easily visible in the 2D
diffractograms measured with small
variation in the orientation of the shell
(three arrows).

A heart with a brain
The heart of the Empyrean is a new revolutionary highresolution goniometer evolving upon a long PANalytical
tradition in precision goniometers. It makes use of the
next generation of Direct Optical Encoding System
(DOPS2), featuring precisely aligned Haidenhain encoders
and Path Tracking Technology (PTT) for continuous
advanced motion control based on Digital Signal
Processing (DSP). Due to this advanced motion control
the goniometer offers highest resolution and differential
accuracy and positions its arms faster and more precisely
than ever before.
