Flow cell and environment at the CoSAXS experimental table. (a) The flow cell capillary holder. (b) The aluminium cassette of the capillary holder and (c) a close up indicating where the X-rays and laser are directed. The size of the laser spot is ∼0.9 mm FWHM and the X-ray spot is ∼160 µm × 140 µm. (d) The setup at the sample table. Fresh sample is delivered through PEEK tubing by a peristaltic pump. The irradiating laser light arrives through a fiber. The sample holder is placed on an X/Y stage ∼25 cm from the WAXS 1D detector and 2 m from the 2D SAXS detector (outside photograph). |
