Abstract
A vapor stripping cell for the transfer of volatile organic substances from either an aqueous phase of a solids sample dispersed in an aqueous phase to a suitable vapor trapping medium for subsequent gas chromatographic analysis. It comprises a bottle-like cell into which extends a tube terminating adjacent the perimetrical portion of the bottom of said cell for introducing organic substance to be tested. A drive is provided for oscillating the bottom of said cell while maintaining the top substantially stationary to spread said substances substantially uniformly on the inner surface of said cell.
