Nitrogen 15 Compounds

(natural abundance 0.365%)

Normally Nitrogen-15 is produced by separation of the naturally occurring element. Nitric oxide is the material of choice when separating Nitrogen-15. Enrichment is available to 99.9 atom%. Nitrogen-15 is used in a broad spectrum of research, including the use of simple salts in various agricultural applications to complex amino acids in medical research.
