Clarification on applying for BioSAXS or SAXS/WAXS beamtime in 2024/2
For solutions that are automatically loaded please apply for BioSAXS beamtime where the Coflow Autoloader is used. Exceptions include samples or experiment design not feasible for BioSAXS (such as anomalous scattering, photon energy requirement (>15 KeV), high viscosity, etc.) for which the SAXS/WAXS beamline will maintain a limited capability for automatic liquid handling.
SEC-SAXS for proteins should be on BioSAXS
Batch measurements for samples in solution should typically be on the BioSAXS beamline
Solution samples in static capillaries can be used on BioSAXS or SAXS/WAXS
