Calcote and King considered only positive ions formed by
thermal ionization in their equilibrium calculations.
The
thermal ionization of gaseous elements at high temperatures: a confirmation of Saha theory.
The slope of the initial part of the plot characterizes the activation energy value [DELTA]E for
thermal ionization of the trap, and the value 1n ([I.sub.tn]/[I.sub.0])--the probability of the tunnelling process from the excited state of the centre.
The CC's findings specify that the acquisition of GV Instruments would significantly affect the markets for gas IRMS and
thermal ionization mass spectrometry (TIMS) instruments.
They analyzed lead concentrations using high-resolution inductively coupled plasma mass spectrometry to make preliminary isotopic measurements, followed by
thermal ionization mass spectrometry measurements.
The use of this method is likely to become more widespread as a result of the development of the Negative
Thermal Ionization Mass Spectrometry developed in the 1990s.
Isotope ratio measurements of urinary calcium with a
thermal ionization probe in a quadrupole mass spectrometer.
NIST developed the isotope dilution
thermal ionization mass spectrometry (IDMS) method for sulfur measurement in 1984.
