A method has been developed for measuring small differences between the vapour pressures of two samples. V.p. differences were determined between water samples with a high concentration of oxygen-18 ( H 2 0 1 8 and D 2 0 1 8 ) and samples with a low concentration in the temperature range 15-90°C. Differences between the vapour pressures of water containing -55 % 0 1 7 and samples containing high concentrations of 0 1 6 and 0 1 8 respectively, in the range 40-90°C, have also been measured. Using these results, vapour pressure ratios between the pure isotopic species were calculated.* i.e. the ratio of vapour pressure of water containing 100 % oxygen-16 to that of labelled water.

“…The low natural abundance of 18 O, energy extensive distillation processes and difficult production processes of [ 18 O]H 2 O (Dostrovsky et al, 1952a;Dostrovsky et al, 1952b) make this target compound rare and expensive.…”

Die Isotopen‐Anreicherung in gegenströmenden Phasen kann mit den partiellen Differentialgleichungen von Cohen berechnet werden. Um die Trennung der Sauerstoff‐Isotope bei der Gegenstromdestillation von Wasser quantitativ zu beschreiben, wurden die erweiterten Cohen‐Gleichungen mittels eines auf dem Runge/Kutta‐Verfahren basierenden Rechenprogramms numerisch integriert. Das Programm ermöglicht es, stationäre und nichtstationäre Isotopen‐Anreicherungen bei Verstärker‐ und Abtriebssäulen sowie bei Kombinationen beider Typen zu berechnen.
