Method/Apparatus/Procedure:
A 1 to 15 volume ratio mixture of heavy water and tetrachloromethane was introduced into an equilibration flask and then lowered into the water thermostat bath. The assembly was shaken mechanically for about 90 minutes at constant temperature. The amount of heavy water in the organic phase was determined by a modified Karl Fischer titration method. The determinations were done in triplicate. The description was taken from a secondary source [1]. The original report is not available from Columbia University.

Estimated Errors:
Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): ±0.1 × 10-5 avg. dev.
