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. These x-rays are then gathered by the X-ray detector and converted into “useful” information. Elemental maps can be obtained for each element of interest and use varying color intensities to visually show the concentrations of a specific element across the area being inspected. Elements that are present in the sample may be missed, and elements that are not present may be falsely identified. Qualitative microanalysis means that the elements present in the sample are identified from their Characteristic X-ray peaks, but their abundances are not determined. Analysis Examples: The two detectors most commonly used include the Secondary Electron Det… SEM-EDX can be used to provide surface elemental composition information of areas as small as nanometers in diameter. • Contamination (Residue) Analysis An electron source, located at the top of the column, produces electrons, which pass through the column and are incident upon the specimen. This detector converts the electrons reflected by the specimen surface into a signal that can be displayed as an image on a monitor. We are here to help, just ask! will absorb more electrons than an element with a lower atomic number thus, for example, areas consisting of carbon (C) will appear much darker on the gray scale than an area containing lead (Pb). Specifically, the SEM column and chamber can be observed in the center of the image with the secondary electron and backscatter detectors found attached to the left side of the chamber and the X-ray detector attached to the right side of the chamber. Uncompromising Integrity. Subsequently these images can be captured as a photograph, if desired. Specialized detectors receive these electrons and process the signal into a usable format. Material Solutions. In both cases, areas of interest can be observed aerially or in cross section. A finely tuned electron beam scans the sample and monitors the reflected electrons from the sample surface. SEM produces images of high resolution and detailed depth of field unlike those attainable using normal optical microscopy. EDX can be utilized for qualitative (the type of elements) and also quantitative (the percentage of the concentration of individual elements of the sample) analysis.

The new SEM and EDAX EDS equipment at Laboratory Testing is particularly helpful in microanalysis and analyzing small areas of interest on samples. Scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDS) comprise When the sample in the SEM is hit with high energy electrons, x-rays are produced from the sample. The X-ray detector, or more specifically, the EDS technique is used to qualitatively and most of the time “semi-quantitatively” determine the elemental composition of an area of interest which was visually identified and observed using the secondary electron and backscatter detectors mentioned above. As a result, the EDS technique can detect elements from carbon (C) to uranium (U) in quantities as low as 1.0 wt%. SEM images, as well as any “captured” photographs, are grayscale in appearance as opposed to color because the electrons being detected are actually beyond the light spectrum. SEM/EDXA provides qualitative elemental analysis and element localization on samples being analysed. SEM images show simple contrasts between organic-based and metallic-based materials and thus instantly provide a great deal of information about the area being inspected. Backscatter – The backscatter detector operates similar to the secondary electron detector as it also “reads” electrons that are being reflected by the test specimen and displays them for observation and / or photography. 1.3.2 SEM used for this study should conform to those limitations outlined in Test Method F1372 and should have a minimum point-to-point resolution of 30 nm.
