Web2) Slice the PET samples to 1 to 2 mm thickness and 5mm x 1 cm. 3) Prepare Silica samples by sprinkling a small amount of silica powder on scotch tape and sealing the tape with a second piece of tape so that no silica can escape. The thinnest possible layer is needed. 4) Mount samples on the SAXS sample holder sheets. 5) Run the SAXS measurement Web20-100 mM PBS, Tris, HEPES, etc. PBS is preferred if possible. Salt concentration < 1M, typically 150-200 mM. Avoid radical scavengers (glycerol, DTT, etc) unless needed for the …

WebThe first step involves creating a scattergram, where total scattering intensity will be plotted against frame number. To do so, go to the Files tab and select all the processed … WebMar 20, 2014 · c. This optimal Z value will not change for any of the scans of your sample 7. You might want to record the optimized value of Theta as Tilt(sample) a. Tilt(sample) indicates the Theta value when the physical surface of the sample is parallel to the X-ray beam b. If the tilt of the substrate peak (determined later) is significantly different than tax rate lees summit mo
