Lecture: "Foremost revelations of Space and Earth Science disclosed by Mass Analysis"

2013-12-20 (Fri) 1:00 p.m. - 8:00 p.m.

When it comes to isotopic ratios, substances in our solar system are surprisingly similar. By making use of this characteristic, by detecting tiny differences in isotopic ratios (0.01-0.1%), one can learn the origin, age, and chemical changes, such as evaporation and condensation, the substances have undergone. Generally speaking, isotopic ratios are difficult to analyze by chemical separation methods. Therefore, mass analysis is used instead.
In this seminar, under the title of "The Foremost Revelations of Space and Earth Science disclosed by Mass Analysis," researchers at the forefront of universe, planet, and earth science fields will talk, in an easy-to-understand manner, about what they have found, current mysteries, and equipment necessary for solving such mysteries. Sound interesting? Why don't you join us?
Isotopic ratio
"One of two or more forms of a chemical element having the same number of protons, or the same atomic number, but having different numbers of neutrons, or different atomic weights." The abundance ratio of a nuclide is the ratio of the number of atoms of one isotope to the number of atoms of another isotope of the same chemical element, often referred to just a abundance.
