The Kevex is a fine XRF machine proved to be very useful but eventually became too costly to manufacture. Production started in 1990 and continued until 2000. It is one of three instruments that still have full support from Kevex (now Thermo Electron.) ...
X-ray fluorescence is a non-destructive technique that can identify and quantify elemental constituents of solids, liquids, and thin films. XRF is sensitive to elements with atomic numbers from sodium to uranium and concentrations from tens of ppm to 100 wt %. -rays from an X-ray tube excite atoms in the sample and cause them to emit X-rays with energies characteristic of the atoms. With appropriate reference standards, accurate quantification of the elemental composition of both solid and liquid samples can be performed.
X-rays from a tungsten anode or molybdenum tube impinge the sample surface at a glancing angle, within the critical angle for total external reflectance, and excite the electrons on atoms in the top few monolayers of the sample, causing them to emit photons (fluoresce). The X-ray photons emitted by the surface atoms have energies that are characteristic of the particular element.

Kevex Instruments Inc is a manufacturer of X-ray elemental analyzers, capable of analyzing sample sizes ranging from microns to millimeters, thickness from angstroms to microns, and elemental concentrations from PPM to weight percents. Specializing in the fields of electron-beam microanalysis, bulk and micro-focus XRF, and automated systems for process monitoring and control, Kevex leads the way with patented innovations such as the Quantum atmospheric thin window, the Superdry no-LN detector, and the PXS microfocus x-ray source which opened up the new technology of x-ray microfluorescence (XRMF). Sigma Gold Microanalyzer- Sigma provides a microanalyzer capable of spectral and image quantification, elemental mapping, feature analysis, EM column and stage automation.
