1.High flux mode for integrated measurements of SAXS/WAXS/UV-Vis-absorption/Refractive-index/Multi-angle-light-scattering (MALS) with an online high-performance liquid chromatography (HPLC) instrument, suitable for exploring biomacromolecular solution structures of a wide length scalestructural kinetics down to microsecond time scale. 2.Ultra SAXS (USAXS) mode for resolving hierarchical structures of bio-machinery assembly up to a few m length scale. 3.Anomalous SAXS mode for metalmineral distributions (including calcium) in bio organelledrug carriers.
