Add to ORKGSamples of a certain stable compound of accurately known concentrations of nitrogen-15 may be used for the quality control of ~(15)N products in the isotopic separation plant. The present investigation aims to prepare a sample of ammonium sulfate with nitrogen-15 concentration of about 98 atom％ ...101348-135
