3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Wavelength dispersion wavelengthdispersive
X-ray diffraction occurs by splitting space dispersion, said dispersion of crystals, also called wavelength dispersion.
3.2
X-ray fluorescence fluorescentX-ray
Atomic energy is higher than the inner electron binding energy of high-energy X-rays collide with atoms, atomic inner electron expelled and the emergence of a
Hole, so that the whole system is in an unstable atomic excited states, when compared with the outer electron transition to the inner hole, the energy release is not an atom
Absorbed but discharged in the form of radiation, it will produce X-ray fluorescence.
3.3
Monitoring sample specimenforcalibrationofinstrument
Instrument for correcting X-ray intensity drift samples, requiring elemental analysis line has adequate strength and long-term stability.
3.4
Standard sample specimenforcalibrationcurve
A sample of known composition and content of work for drawing curves, the sample should be in the chemical composition, physical properties and other aspects of a
Cause. The concentration of the standard sample should cover the concentration range of Quantitative Analysis.
3.5
Background background
Line superimposed on a continuous spectrum analysis, mainly from the scattering of the radiation incident on the sample.
