Experimental set-up implemented on the hard X-ray branch of the Metrology beamline. (a) Geometrical set-up for the biomolecules footprinting experiments on the hard X-ray branch of the Metrology beamline; (b) calculated pink beam footprint at the sample position for 430 mA current and considering the transmissions of a 150 µm-thick Be window, a 900 mm air path and a 10 µm-thick quartz capillary. Curves were calculated using the SpotX software, as described previously (Moreno & Idir, 2001). The white rectangle represents the useful area of the capillary. The corresponding spectrum impinging on the solution is given on linear (continuous line) and logarithmic (dashed line) scales. |
