  • Patent number: 5814128
    Abstract: A water management system removes water vapor from the analyte slug that is desorbed from the trap. The water management system includes a device having a passage through which the volatile organic chemicals and water pass, the passage being designed to remove water vapor by swirling action on the stream. The amount of water removed is more than can be accounted for by simple condensation. The invention also includes the adjustment of the temperature of the water management device during the sample concentration cycle to prevent undesired condensation prior to desorption.
    Type: Grant

  • Patent number: 5261937
    Abstract: A filter for preventing foam and debris from accumulation on the trap used in sample concentration apparatus is disclosed. The filter is preferably a sintered metal frit removably inserted in the concentrator inlet on a sparge vessel. The filter also serves as a check valve for preventing water vapor or residual analytes in the sparge vessel from contaminating dry gas or other external samples which pass through the concentrator inlet.
