Working Principle of X-Ray Crystal Analyzer

The operational foundation of the X-ray crystal analyzer lies in Bragg's law. According to this principle, when X-rays are directed onto a crystalline sample, diffraction occurs at specific angles, generating distinct diffraction spots or peaks. By precisely measuring the positions and intensities of these diffraction signals, it becomes possible to deduce the internal structure and composition of the crystal.
