WebThe SAXS measurements were conducted at the BL23A beamline, National Synchrotron Radiation Research Center (NSRRC), Taiwan, with high-flux collimated X-rays of 15 keV and a beam size of ~500 μm. The SAXS specimens were ground to a thickness of ~20 μm at the detected area for optimal transmission. WebJun 24, 2012 · Everybody is talking about optimal sample thickness in bioSAXS. But what are the criterias for the minimum (!) sample thickness. Let's assume 12.4keV standard …
WebFor data reduction, the information of sample transmission is needed in Eq. (1). In optimizing the sample thickness in a SAXS measurement, we take the thickness derivative to (1), d(Is)/dt=0, and obtain an optimize sample transmission T = e-1 for the best scattering intensity. From the optimized T, we can deduce the optimum sample thickness t ... http://prism.mit.edu/xray/documents/Bruker%20HRXRD%20XRR%20SOP.pdf
WebIt is difficult to define minimum sample requirement for SEC-SAXS. That is depending on how the sample distributes during SEC as well as injection volume of sample, the sample … WebSAXS data ( Fig. 4A) showed that multilamellar structures are still present with the characteristic three equally-spaced peaks at q = 0.046 Å −1, 0.093 Å −1, and 0.138 Å −1. Interestingly, the d -spacing measured is d001 = 2π/ q001 = 14 nm. This spacing is three times larger than the interlamellar spacing obtained with DOPC liposomes.
