X-ray diffraction is the best method for phase identification. Can all crystal materials be accurately identified by diffraction?
It is not entirely true that the world's substances are difficult to obtain pure substances. Because of the environment, they are more or less in other solute elements and are combined with them. It is difficult to find standard data, but he is close to a certain These standard phases give false phase identification results. At the same time, measurement conditions, sample preparation conditions, and environmental changes may cause different diffraction spectra of the same substance to form false detections.
If there is no chemical criterion, this error cannot be found at all!
Elemental criteria can avoid false positive errors due to different elements and different measurement conditions. In the actual test, there are many requirements for the elemental criteria: testing all elements, analyzing the data accurately, analyzing quickly, making samples easy, and the instrument is cheap.
The PANalytical Epsilon1 benchtop XRF spectrometer provides the results of analysis of all elements in a sample at a time, with extremely high analytical accuracy (viewing data), fast analysis (3 minutes), and extremely easy sample preparation (just placing the sample) On the surface, each sample can be measured by a diffractometer. At the same time, the element information can be obtained by using the E1 energy dispersive spectrometer, which can prevent erroneous retrieval results and make the phase identification result accurate.
