For portable XRF spectrometers, copper target is usually bombared with high energy electrons, that are produced either by impact laser or by pyroelectric crystals. [ 4 ] [ 5 ] Alternatively, gamma ray sources, based on radioactive isotopes (such as 109 Cd, 57 Co, 55 Fe, 238 Pu and 241 Am) can be used without the need for an elaborate power ...

Later NASA developments did lead to an X-ray spectrographic unit that did make the desired moon soil analysis. The Norelco efforts faded but the use of X-ray spectroscopy in units known as XRF instruments continued to grow. With a boost from NASA, units were finally reduced to handheld size and are seeing widespread use.

A microfocus X-ray source for improved EDS and XRF analysis in the SEM. Procop, Mathias, Vasile-Dan Hodoroaba, and Vanessa Rackwitz.
Micro x-ray fluorescence (μXRF) is an elemental analysis technique that relies on the same principles as x-ray fluorescence (XRF). Synchrotron X-rays may be used to provide elemental imaging with biological samples. [1] The spatial resolution diameter of micro x-ray fluorescence is many orders of magnitude smaller than that of conventional XRF.
Analysis is generally limited to a very small area of the sample, although modern automated equipment often use grid patterns for larger analysis areas. [ 3 ] The technique cannot distinguish between isotopes of elements as the electron configuration of isotopes of an element are identical.
Malvern Panalytical is a Spectris plc company. [6] The company is a manufacturer and supplier of laboratory analytical instruments. [7] [8] It has been influential in the development of the Malvern Correlator, [9] and it remains notable for its work in the advancement of particle sizing technology. [10]
Backscatter technology is based on the Compton scattering effect of X-rays, a form of ionizing radiation.Unlike a traditional X-ray machine, which relies on the transmission of X-rays through the object, backscatter X-ray detects the radiation that reflects from the object and forms an image.
