Analysis of the contributions to background X-ray scattering when using 100 and 200 µm-diameter borosilicate glass capillaries. (a) Measured X-ray scattering, S(q), from empty 100 µm (blue) and 200 µm (red) diameter borosilicate glass capillaries after azimuthal integration. The X-ray scattering has arbitrary units (a.u.) and ![[q = 4\pi \sin(\theta)/\lambda = 4\pi /2d]](teximages/ap5048fi1.svg){kind=small} , where 2θ is the angle of deflection of the X-rays and 1/d is the resolution quoted in X-ray crystallography, such that q = 2.0 Å−1 corresponds approximately to 3.1 Å resolution. (b) Measured X-ray scattering from a 100 µm-diameter flow cell containing LCP-grown microcrystals of CcO (mustard) and the best decomposition (black dashed line) of this scattering into its three scattering components from LCP (black solid line), borosilicate glass (blue) and air (black dotted line). (c) Measured X-ray scattering from a 200 µm-diameter flow cell containing LCP-grown microcrystals of CcO (mustard) and the best decomposition (black dashed line) of this scattering into its three scattering components of LCP (black solid line), borosilicate glass (red) and air (black dotted line). Air measurements were made without any object at the sample position, whereas LCP scattering was recorded from a homogeneous LCP sample extruded below the glass of a 200 µm-diameter flow cell. Air scattering was removed from the LCP and glass in panels (b) and (c). A larger background contribution from the borosilicate glass is observed when using the 100 µm-diameter capillary relative to the 200 µm glass capillary. |
