Energy-dispersive X-ray spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA or EDAX) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of some source of X-ray excitation and ...
EDX spectrometers can also use miniature X-ray tubes or gamma sources, which makes them cheaper and allows miniaturization and portability. This type of instrument is commonly used for portable quality control screening applications, such as testing toys for lead (Pb) content, sorting scrap metals, and measuring the lead content of residential ...
For example, two EDX spectra were obtained during an investigation into ozone cracking of diaphragm seals in a semiconductor fabrication factory. The EDX spectrum of the crack surface shows the high-oxygen peak compared with a constant sulfur peak. In contrast, the EDX spectrum of the unaffected elastomer surface spectrum shows a relatively low ...
General chemistry (sometimes referred to as "gen chem") is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. [1] The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out ...
EDS or EDX – Energy dispersive X-ray spectroscopy; EELS – Electron energy loss spectroscopy; EFTEM – Energy filtered transmission electron microscopy; EID – Electron induced desorption; EIT and ERT – Electrical impedance tomography and electrical resistivity tomography; EL – Electroluminescence; Electron crystallography
Concerns about contracting bird flu through eggs persist, though “experts state that the risk to the general public is low,” says Nichole Dandrea-Russert, M.S., R.D.N., author and plant-based ...
