ABSTRACT:
In a method for extracting volatile substances from a vaporized liquid in which the vaporized liquid is withdrawn from an extraction chamber, a method of producing the vaporized liquid. The method includes the steps of introducing a carrier gas into the extraction chamber to form a vapor space, and spraying a liquid into the vapor space to form a vaporized liquid. An apparatus for practicing the method includes an extraction chamber in fluid communication with a liquid specimen source, and a liquid injection arrangement extending into the extraction chamber for spraying the liquid from the liquid specimen source in the vapor space to form a vaporized liquid. A carrier gas supply arrangement is provided adjacent to the extraction chamber for introducing carrier gas into the chamber to form a vapor space. The apparatus may further include a specimen chamber for collecting a predetermined amount of liquid prior to spraying.
