Detailed Description

Stores elements.

The elements weights (in the default file) are taken from "Isotopic Compositions of the Elements 1997", Pure Appl. Chem., 70(1), 217-235, 1998. (http://www.iupac.org/reports/1998/7001rosman/)

The isotope distributions (in the default file) are taken from "Atomic weights of the elements. Review 2000" (IUPAC Technical Report) Pure Appl. Chem., 2003, Vol. 75, No. 6, pp. 683-799 doi:10.1351/pac200375060683

This singleton stores all elements. The elements are taken from the publications given above and are stored in share/OpenMS/CHEMISTRY/Elements.xml.

Specific isotopes of elements can be accessed by writing the atomic number of the isotope in brackets followed by the element name, e.g. "(2)H" for deuterium.

Improvement:

include exact mass values for the isotopes (done) and update IsotopeDistribution (Andreas)

add exact isotope distribution based on exact isotope values (Andreas)
