• If you want to use Isotope to develop commercial sites, themes, projects, and applications, the Commercial license is the appropriate license. With this option, your source code is kept proprietary.Isotope fractionation is a process that occurs during chemical reactions as well as during physical processes, and this effect needs to taken into account in most radiocarbon measurements. The effect of isotope fractionation is a partial separation of the different isotopes and results in enrichment of one isotope relative to another.
