Method/Apparatus/Procedure:
A modification of the EPICS procedure was used for measuring Henry's law constants. A precise quantity of tetrachloromethane was injected into serum bottles which contained distilled water. The bottles were incubated for 18 - 24 hours at four desired temperatures in a reciprocating shaker bath. The headspace concentrations of the EPICS bottles were measured by a gas chromatograph which was equipped with a flame ionization detector. The mean of the coefficient of variation values was approximately 4.3 %.
