Notes:
   a  CV = coefficient of variation ( = 100 S.D./mean).

Method/Apparatus/Procedure:
   A modification of the EPICS procedure was used for measuring Henry's law constants. A precise quantity of tetrachloroethene 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 about 4.3 %.

Source and Purity of Materials:
   (1) Alfa Products, ultrapure; greater than 99% pure.
   (2) Distilled.

Estimated Errors:
