NANOGRAPHY Lab Report

X-ray Nanography, or two-dimensional scanning Small Angle X-Ray Scattering (2-D scanning SAXS), is a powerful method for displaying and investigating the microscopic structure of specimens on the μm-scale. For instance, Nanography shows inhomogeneities such as different chemical compositions or varying density within a sample. In this way, Nanography combines the nanoworld with the microworld.

 

A Nanography investigation requires a specimen to be mounted on a motor-driven XY stage, in order to automatically scan the sample through the X-ray beam. Each individual point within the nanograph represents the integral SAXS/WAXS intensity collected by the 2-D detector at this position. The intensity distribution is displayed by means of a color-coded contour plot.
