These components include the X-ray detector, pulse processor to measure the voltage with respect to X-ray energies, and a computer system. There are three principal components present in basic EDAX systems. This method gives accurate results for not only element detection, but also to determine their concentration after maintaining the ideal instrumental conditions. Hence, this technique also can be used to measure the energy of emitted X-rays. The X-rays are generated according to the characteristics and nature of the elements present in the sample. The basic principle of EDAX is a generation of X-rays from a specimen through the electron beam. This method has found some limitations with regard to accurate dimensional and elemental characterization ( Hodoroaba et al., 2014b). The individual separated nanoparticles are deposited on a suitable substrate that does not interfere in the characterization of nanoparticles ( Kim et al., 2012). In this technique, the nanoparticles are analyzed by activation using an EDS X-ray spectrophotometer, which is generally present in modern SEM. Tekade, in Basic Fundamentals of Drug Delivery, 2019 10.3.3 Energy-Dispersive X-Ray AnalysisĮnergy-dispersive X-ray analysis (EDAX) is a technique used for the measurement of nanoparticles by SEM.
