• lifetime
  • After a short delay (the average represented as the fluorescence lifetime τ {\displaystyle \tau } ), it comes down to a lower state by losing some of the energy as heat and emitting the rest of the energy as another photon. (wikipedia.org)
  • metals
  • These facts, and the composition of the dagger had long suggested a meteoritic origin, however, evidence for its meteoritic origin was not entirely conclusive until June 2016 when researchers using x-ray fluorescence spectrometry confirmed similar proportions of metals (Iron, 10% nickel, and 0.6% cobalt) in a meteorite discovered in the area, deposited by an ancient meteor shower.

  • mass
  • However, compared with other types of mass spectrometry, such as thermal ionization mass spectrometry (TIMS) and glow discharge mass spectrometry (GD-MS), ICP-MS introduces many interfering species: argon from the plasma, component gases of air that leak through the cone orifices, and contamination from glassware and the cones.

  • Analysis
  • X-ray fluorescence spectrometric methods were used in the analysis of eight Argonne Premium Coal Samples. (usgs.gov)
  • This book brings together the knowledge and expertise of internationally recognised scientists with practical experience of in situ analysis using portable X-ray fluorescence technology. (rsc.org)
  • Thus, once deployed for use in a facility, the fluorescence information can be fiberoptically transmitted to a remote location, where data processing and analysis can be performed. (wikipedia.org)
  • light
  • even before the laser existed, when conventional light sources were used to excite the fluorescence. (wikipedia.org)
  • SOFIA solves the problem of low collection efficiency, as it collects nearly all of the fluorescent light produced from the sample being analyzed, increasing the amount of fluorescence signal by around a factor of 10 over conventional apparatus. (wikipedia.org)
  • sample
  • Surround optical-fiber immunoassay (SOFIA) is an ultrasensitive, in vitro diagnostic platform incorporating a surround optical-fiber assembly that captures fluorescence emissions from an entire sample. (wikipedia.org)
