New Developments in Laboratory SAXS Instruments — •Bastian Arlt¹ and Andreas Keilbach² — ¹Anton Paar Germany GmbH, Hellmuth-Hirth-Straße 6, D-73760 Ostfildern — ²Anton Paar GmbH, Anton-Paar-Straße 20, A-8054 Graz

Surfactants, dispersions, polymer or protein solutions and (micro-) emulsions are intensively investigated systems in current science. Consequently, an essential point is the careful characterization of these systems in-situ. The small angle X-ray scattering (SAXS) technique offers precise and fast measurements to investigate parameters such as size, shape, interaction effects of particles in solution. Thus, SAXS is a complementary method to TEM, AFM, or NMR techniques. SAXS measurements are performed at synchrotron facilities or, thanks to recent developments, using laboratory instruments which have become an excellent alternative.

We are going to present the latest developments and trends in the field of laboratory SAXS instruments. Thanks to high-flux X-ray sources, short exposure times are possible. Additionally, Anton Paar has explored novel techniques in sample positioning which are commonly known from synchrotron measuring stations and allow extending the available detection range and resolving smallest dimensions.
