What is SAXS for?

X-ray Scattering is an analytical technique giving access to information about the structure of materials at the nano- and micro-scale.

In modern instruments, measurement can be performed on samples in a controlled environment, such as temperature, stress, pressure, concentration, allowing for understanding the link between structure and function.

Advantages of SAXS

X-rays penetrate materials opaque in the visible spectrum and thus allow to probe the structure inside the material. No cross-sectional or microtome preparation is involved. Used in grazing incidence mode the technique can probe structured surfaces.

The very short wavelength (sub-nanometer) of x-rays gives the technique sensitivity to structure even at the crystalline level and up to dimensions [lengthscales] of several hundred nanometer.

X-ray Scattering typically probes a mm3 of sample assuring that the structural information collected is representative for the sample.
