Microfluidics for SAXS experiments

Abstract
SAXS is a powerful technique providing unique information on the nanostructure and kinetics of condensed matter. Recently, novel SAXS applications in the areas of very short time-scales, very broad resolution range and ultra-small beam sizes have been demonstrated. However, the brightness of such a source must adequately be employed and entirely new requirements are demanded with respect to sample environment. This is particularly important for combined experiments like Raman, IR, in situ preparation, at the micron/submicron level. In this communication, two microfluidic devices will be presented. The first is a rapid mixing device with a free jet flow to investigate ultrafast chemical reactions by SAXS. The second is a microfluidic cell for the study of localized biological nanostructures by means of SAXS and LT.
