SEM-EDX analysis. Unlike BSE, SE and TE, X-rays are electromagnetic radiation, just like light, and consist of photons.To detect them, the latest systems use the so-called silicon-drift detectors (SDDs).These are superior to the conventional Si(Li) detectors due to higher count rates, better resolution, and faster analytical capabilities. Holes have a positive charge and, in the second step of the process, attract the negatively-charged electrons from higher-energy shells. EDX staat voor Energy-Dispersive X-ray spectroscopy en word ook wel EDS genoemd. Dit is een apparaat waarmee we een bundel elektronen extreem goed focusseren in één punt. The EDS technique detects x-rays emitted from the sample during bombardment by an electron beam to characterize the elemental composition of the analyzed volume. The higher the solid angle between the detector and the sample, the higher the X-rays’ detection probability, and therefore the likelihood of acquiring the best results. The EDS utilizes the latest SDD detector technology for LN-free operation and very high count rates for fast analysis and x-ray mapping. SEM-EDX is powerful in problem-solving instruments with variety of possible applications. Nanoparticle Analysis - Correlating EDX, AFM and SEM Data. Thermo Fisher Scientific.
