Method/Apparatus/Procedure:
A steady flow of anaesthetic vapor was bubbled through water, allowing 45 minutes for equilibration. The concentration in the gas mixture was in the range 1-3 % (v/v) 2-bromo-2-chloro-1,1,1-tri-fluoroethane. A Riken 18A refractometer provided accurate estimations of the gaseous concentrations of 2-bromo-2-chloro-1,1,1-trifluoroethane. Five samples of aqueous solutions were analyzed by gas chromatography. The chromatograph was equipped with a flame ionization detector and apotentiometric recorder.
Source and Purity of Materials:
- ICI Pharmaceuticals, used as received.
