Introduction The scientific laboratory of the "Prussian Palaces und Gardens Foundation Berlin-Brandenburg (SPSG)" is engaged in the material analysis of German paintings from the 15th and 16th century, especially the works by Lukas Cranach the Elder (1472-1553) and the Younger (1515-1586). An SEM, or scanning electron microscope, is a type of microscope that produces images of a sample by scanning the surface with a focused beam of electrons rather than the usual optical means.This allows for imaging at very high magnifications, typically from about 10 to 500,000 times, with a clarity previously not possible. Fig. Scanning electron microscopy in combination with energy-dispersive X-ray spectrometry (SEM/EDX) is a well-established and versatile method for the characterization of heterogeneous catalysts, especially Ag catalysts. Energy Dispersive X-Ray Spectroscopy (EDS or EDX) is a chemical microanalysis technique used in conjunction with scanning electron microscopy (SEM). In this way, X-rays are a “fingerprint” of each element and can be used to identify the type of elements that exist in a sample. Thermo Fisher Scientific. Read 21 answers by scientists with 40 recommendations from their colleagues to the question asked by Stella Dozie on Apr 10, 2016 SEM Imaging Process • Electron gun generates high energy electrons which are focused into a fine beam, which is scanned across the surface of the specimen. The data that is generated by EDX analysis consists of spectra with peaks corresponding to all the different elements that are present in the sample. For example, backscattered electrons produce images with contrast that carries information on the differences in atomic number; secondary electrons give topographic information; cathodoluminescence can give information on the electronic structure and the chemical composition of materials; and transmitted electrons can describe the sample’s inner structure and crystallography. In our and other previous research it was shown, that SEM-EDX becomes a valuable tool for a precise investigation of the elemental composition, as well as distribution of elements in different biomasses [6, 18, 39]. Read 15 answers by scientists with 36 recommendations from their colleagues to the question asked by Kristine Salazar Salvador on Sep 2, 2016 Vanaf een bepaalde diepte komen er geen elektronen meer uit het sample omdat ze geabsorbeerd worden. When the sample in the SEM is hit with high energy electrons, x-rays are produced from the sample. The advantages of SEM over light microscopy include much higher magnification (>100,000X) and greater depth of field up to 100 times that of light microscopy. 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. 1.4 The SEM provides images that can range in scale from a low magnification (for example, 15×) to a high magnification (for example, 50 000× or greater) of concrete specimens such as fragments, polished surfaces, or powders. Energy-dispersive spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample.
