Notes:
   1  Gas-liquid system analysis parameter, from calibration measurements.

Method/Apparatus/Procedure:
   A 5 μL trichloromethane sample was injected into a 2.3 liter equilibration cell containing distilled water. After the cell was shaken vigorously for about 5 minutes, the homogeneity of the liquid sample was maintained with a magnetic stirrer. Compressed air  was passed through the cell and the gas flow was measured with a soap film flowmeter. The trichloromethane content was extracted and analyzed using a dual flame ionization detector gas chromatograph.

Source and Purity of Materials:
   (1) Source and purity not given.
   (2) Distilled.

Estimated Errors:
   Solubility: ± 10.0 %.
   Temperature: ± 0.5 K.
