Instrumental Isotopic Fractionation
2014In mass spectrometry, the term ‘instrumental isotopic fractionation’ is recommended to describe the sum of the effects in a mass spectrometer occurring during sample introduction, ion formation, ion extraction, ion separation and ion detection leading to a difference of the measured isotope ratio from the true isotope ratio in a sample.

The Fractionation of the Light Isotopes
1974Modern mass spectrometers make it possible to measure variations in isotopic abundances to the order of 1 part in 104. With this sort of equipment, one might undertake to measure the isotopic composition of various elements in various natural mineral compounds, for example, the isotopic composition of S in natural sulfides, in native S, in S found in ...

Isotopic fractionation in sputtering
1990Isotopic fractionation due to sputtering has been investigated via a collector type experiment in which targets of known isotopic composition have been bombarded with several keV Ar+ and Xe+ ions with fluences down to 3.0x1014 ions/cm2 , believed to be the lowest fluences for which such detailed measurements have ever been made.
