Common XRF Definitions
Helium purge,
v. Physics
Helium purge,
v. Physics 1. the process of
replacing the air present surrounding the x-ray tube and detector with helium
gas to permit the direct analysis of magnesium, aluminum, silicon, phosphorus
and low levels of sulfur in a variety of sample types. 2. the method preferred
over vacuum purge systems for analysis of magnesium, aluminum, silicon,
phosphorus and sulfur resulting from its higher reliability and reduced
potential for instrument contamination. 3. the technique employed by handheld
Thermo Scientific NITON
® XRF analyzers for light element analysis in metal alloys,
mining and soil samples.

the instrument is connected to a test stand, as well as conduct simultaneous datalogging of
measurement data.
ni·ton,
n. Physics
ni·ton, n. Physics 1. archaic
term for radon gas. 2. now part of Thermo

Vacuum purge, v. Physics
Vacuum purge, v.
Physics 1. the process of evacuating
the air present
surrounding the x-ray tube and detector
to permit the direct
analysis of magnesium, aluminum, and silicon
in metal alloys.
2. an inferior method for light element
analysis, as compared
to helium purge, because of its reduced
reliability and
higher potential for instrument
contamination.
