High precision cerium isotope analysis by thermal

In this study, a novel method has been developed for high precision measurement of Ce isotope ratios by thermal ionization mass spectrometry (TIMS) as Ce +. A newly developed film porous ion emitter (FPIE) was used to enhance the ionization of Ce as Ce + ions.

First, you should notice that simply mass on the x axis but m/z, where m is the mass and z is the charge. What the spectrometer actually measures is mass/charge (m/z) ratio. Sounds complicated, but its notbecause the majority of the ions produced during MS have a charge of 1, m/z is normally equal to the mass of the molecule

The relative abundances of different isotopes are then used to describe the chemical fractionation of different isotopes, travel in different reservoirs of non radiogenic isotopes, and age or origins of solar system objects by the presence of radiogenic daughter isotopes.
Elemental analysis is a predominant application of TIMS as it gives reliable isotopic ratios. Following the trend of decreasing ionization energy, elements located towards the bottom left of the periodic table are

OverviewThermal ionization mass spectrometrySee also

Thermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are ionized.
Thermal ionization is used to make simple ion sources, for mass spectrometry and for generating ion beams. Thermal ionization has seen extensive use in determining atomic weights, in addition to being used in many geological/nuclear applications.
