The X-ray Orientation Analyzer is a versatile technology that can be used to identify any crystalline material, such as most minerals.

It can also be used to quantify the proportion of different minerals or indeed many other substances when they are present in the mixture.

Clay mineral and clay particle size analysis
We specialize in the analysis of clay minerals by XRPD. Typically, clay mineral analysis involves the separation of the clay size fraction (usually < 2 microns) from the sample. Once obtained, the clay fraction was prepared by collecting it on a filter and transferring the clay layer onto the slide substrate. This so-called "filter stripping" process enhances the preferred orientation of the platy clay particles, which helps to obtain good diffraction signals from the diagnostic surface of the clay mineral. It is also the best way to make a homogeneous sample, and it is essential to quantify the results. These oriented samples were run on an X-ray orientation analyzer (air dried) and then run again after various treatments, such as solvation with ethylene glycol, and heated to the specified temperature for the indicated time. Other treatments may be suitable for identifying certain clay minerals. Peak position, shape and strength, and variations between these treatments are diagnostic for identifying different clay minerals. Qualitative analysis can be performed by intensity ratio method, wherein the integrated intensity (peak area) of the selected clay mineral peaks is defined by a mineral strength factor (MIF) or a more general predetermined ratio constant and their weight in the mixture.

The precise identification of clay minerals is the first step in the analysis of any clay mineral. We have been based on years of experience in the interpretation of clay mineral diffraction patterns and their response to various auxiliary treatments.
