Method/Apparatus/Procedure:
   A gas chromatographic analysis combined with a crushed ampoule technique was used. The solubility values were determined by equilibrating trichloromethane with water in a sealed ampoule. Then, after the ampoules were broken, the samples were analyzed using a gas chromatograph equipped with a flame ionization detector.
