But, we also learned that two atoms of the same element can have different numbers of neutrons than each other. 2019-03-17 ISC-Sciences produces Isotopic Standards and Certified Reference Materials for Isotope Dilution Analysis and ICP-MS and/or GC-MS Isotopic applications.

The Isotope Standards are prepared from stable isotopes and certified according to ISO 17034 and ISO/IEC 17025. Chemistry is the study of matter and the changes it undergoes. Here you can browse chemistry videos, articles, and exercises by topic. We keep the library up-to-date, so you may find new or improved material here over time.
