But, we also learned that two atoms of the same element can have different numbers of neutrons than each other. According to ISO 17034 and ISO/IEC 17025, the certified concentration value was determined gravimetrically from a standard characterized by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) using a reference method in a single laboratory [Isotope Dilution Mass Spectrometry (IDMS)] and certified isotopic abundances were determined by measuring the isotope-amount ratios for all isotopes by Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. ISC-Sciences produces Isotopic Standards and Certified Reference Materials for Isotope Dilution Analysis and ICP-MS and/or GC-MS Isotopic applications.

(Since atomic mass = mass protons + mass neutrons) – These isotopes are called carbon-12, carbon-13 and carbon-14. Alternatively, they may be written 12C, 13C and 14C.
