Membrane chemical degradation characterization techniques

Energy dispersive X-ray spectroscopy (EDX) is used predominantly for elemental analysis or chemical characterization. The advantage of this technique is that it can identify the elemental composition for a small area thus, a profile of element composition can be created across the sample. Since EDX tests are usually conducted in a scanning electron microscope, a composition profile can be directly overlaid onto a secondary scanning electron microscope micrograph. Major elements related to membrane chemical degradation such as fluorine, sulfur, platinum and other metals can be readily detected.
