Method/Apparatus/Procedure:
The multiple equilibration technique was used to measure the Henry's law constant as described by McAuliffe (ref. 1). A known volume of water in a syringe was shaken with a known volume of pure tetrachloromethane. After equilibration of the sample, the headspace was separated and analyzed for the compound of interest. A gas chromatograph fitted with an electron capture detector was used for the analysis.
