The Preparation of Oxygen-17 Enriched Water from Enriched Nitric Oxide Gas

摘要

A process and equipment designed to produce water enriched in oxygen-17 and oxygen-18 isotopes from correspondingly enriched nitric oxide gas is described. Approximately 1450 ml of high purity enriched water containing 1 to 3% oxygen-17 and 10 to 20% oxygen-18 have been produced for use primarily in nuclear mag¬netic resonance experimentation. Substantial quantities of nitrogen enriched in nitrogeri-15 have been recovered as a by-product.
