What you get:

The powder X-ray diffraction is a qualitative and quantitative method for physico-chemical analysis. This technique allows to determine the nature of each crystalline phase in a sample but also to trace the structure of the analyzed system (lattice parameters, atomic positions, ...)

Principle:

The X-ray diffraction is an analytical technique based on X-ray diffraction by material. The general method involves bombarding the sample with X-rays and analyzing the X-ray intensity accordingly its spacial distribution. Difused X-rays interfere with each other, then generating maxima intensity in certain directions, this is called diffraction. Records of the detected intensity as a function of the 2θ angle of the beam is achived.

Materials: All crystallised materials (minerals, metals, ceramics, organic).

How to use them: The diffraction apparatus are under self-service conditions after agreement (training required).

Options: Opportunities to use different types of sample holder.
