More information about FTIR can be found on our FTIR analysis page. Jocelyn 'Josie' Packard (born Li Chun Fung) was the owner of the Packard Sawmill following the apparent death of her husband, Andrew Packard. EDS is a powerful tool for microanalysis of elemental constituents.ĮDS analysis is usually a destructive technique due to cutting the sample to size to fit into the chamber.ĮDS can also be referred to as EDX or EDAX analysis.ĮDS analysis is useful in identifying certain types of polymeric materials as shown here: EDS Analysis of Polymers.įor organic materials analysis and/or identification, Fourier Transform Infrared Spectroscopy or FTIR is more suitable. By analyzing the emitted x-rays, the elemental composition of the sample can be determined. The vacated positions are filled by higher energy electrons which emit x-rays in the process. These electrons collide with the electrons within the sample, causing some of them to be knocked out of their orbits. During EDS a sample is exposed to an electron beam inside a scanning electron microscope (SEM). Energy dispersive X-ray analysis, also known as EDS analysis, is a technique used to identify the elemental composition of a sample or small area of interest on the sample.
