Description
The small-angle neutron scattering (SANS) diffractometer KWS-2, operated by the Jülich Centre for Neutron Science at Heinz Maier-Leibnitz Zentrum in Garching, is equipped with an in-line size exclusion chromatography (SEC) followed by the multi-angle light scattering (MALS) machine. The established SEC-SANS-MALS setup facilitates the in-situ fractionation of the sample solution, the collection of SANS data, and the analysis of molar mass, subsequently. In addition, a UV-vis spectrometer is installed on the SANS flow cell holder, to examine the sample concentration during SANS data collection. In the present work, the performance of the setup is assessed and optimized, and the work on signal synchronization aims at better management of the multi-task measurement.
