X-Ray Fluorescence Emission Analysis of Slurries
For X-ray fluorescence emission analysis of a difficultly soluble solid, standard procedure is to grind the material and press into pellets. Any inhomogeneity will give inaccurate results, since X-ray sampling is limited to the top layer. For such samples, study in slurried form is suggested. Chemical treatment is eliminated and particle reduction does not need to be great. Because of the continuous stirring, the entire sample is exposed to the X-ray beam. Sampling and accuracy are good, and particle-size effects are minimal.
