Figure 4
Two-dimensional SAXS/WAXS pattern from two crossed rat tail collagen fibres (raw data, no background subtracted). The numbers correspond to different reflections described in the text. The setup used for the measurement was option (b) with a 10 µm beam-defining pinhole, a wavelength of λ = 0.827 Å and a sample to detector distance of L = 253 mm. The beamstop consisted of a lead wire of 0.25 mm diameter at a distance of about 50 mm from the sample. (a) shows the whole pattern with the maximum scattering angle corresponding to 2θ = 32°, and (b) shows the enlarged central region of (a) with the meridional reflections from dry collagen type II (d = 650 Å) up to the 20th order. The total q range is 0.2 nm−1 < q < 40 nm−1. |
