X-Ray Systems, founded in 1992, is traditionally specialized on innovative
system solutions for X-Ray nanostructure analytics. The strong focus on
small-angle X-ray methods - the Otto-Kratky heritage - serves a wide community
of researchers and engineers, who need SAXS and related techniques as practical
and reliable tools in their challenging laboratory practice, and who want to use
the techniques routinely.
Most Burning Questions in Nano-Structural Chemistry and Biology
The paradigm of material science in the 20th century was that X-ray crystallography
provides the ultimate answer for structure. Today, the most burning questions
in nano-structural chemistry and biology are focussed on the non-crystalline,
'amorphous' state and its structure-function relationships in:
- Supramolecular cell biology
- Nanomaterials
- Hetero-phase systems at equilibrium and far from it
- Structure and reactions at surfaces
These and many more phenomena are accessible by small-angle X-ray scattering
(SAXS), as virtually any form and shape, and their transformation, gives a SAXS
signal.
Challenges of Small Angle X-Ray Scattering in the Past
In the past, two main factors have been responsible for the reluctance to exploit
this potential: Firstly, the lack of brilliant laboratory X-ray sources and
cameras. This was only remedied by synchrotron radiation facilities, which have,
however the disadvantage of being far away from everydays laboratory practice.
Secondly, the lack of robust and widely applicable routines for the interpretation
of SAXS data.
Advancement Dramatically Increases Use of Small Angle X-Ray Scattering
Recent advances both in SAXS technology: extremely brilliant and compact laboratory
SAXS systems, detectors and fast data processing, and the combination with complementary
methods, such as calorimetry, pressure scanning, in- situ reaction monitoring,
highthroughput screening, have provided the basis for a dramatically increased
use of SAXS. In addition to becoming a routine tool in laboratory analytics,
this will also improve the intelligent use of synchrotron facilities for truly
cutting-edge investigations.
