Figure 1.

(a) Overall layout of the solution scattering instrumentation at LiX, with the following components: (A) guard slits, (B) flow cell, (C) WAXS chamber, (D) and (E) WAXS detectors, (F) bellow-based SAXS flight path, (G) SAXS detector, and (I) fluorescence detector. A mica-window-terminated beam tube extends the vacuum from the guard slits to just upstream of the flow cell. Another mica window on the nose cone on the WAXS chamber terminates the vacuum in the detector chamber. (b) Photograph of the PCR tube holder being partially loaded into the solution sample handler. Two PCR tubes are visible. (c) Photograph of the complete solution scattering setup at LiX: (A) Staubli six-axis robot, (B) solution scattering sample handler, (C) sample storage unit and (D) HPLC system. The X-ray beam enters from the right. As a reference for scale, the sample storage unit is 45 cm high, 18 cm wide (along the beam direction) and 14 cm deep.
