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 1,1,1-trichloroethane 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:
