Small Angle X-ray Scattering (SAXS) is a common physical method to characterize the structure of materials on the nanoscale. The absolute scattering intensity contains quantitative information related to the mass and density of materials. We studied the absolute scattering intensity calibration method on the 1W2A SAXS station at Beijing Synchrotron Radiation Facility (BSRF) with standards such as glassy carbon and water, and further applied the method to determine the molecular weight of ovalbumin and the porosity of anthracite coal during pyrolysis.
