  • Patent number: 6146595
    Abstract: A closed positive pressure evaporation system for evaporating samples in preparation for analysis comprising a plurality of sample vials where each sample vial has associated therewith an inlet and an outlet. An chamber is provided having a heat source and a holder for positioning and holding the sample vials with reference to the heat source. A distribution manifold is connected via tubing to the inlet of each sample vial for distributing purified inert gas, such as Nitrogen, to each sample vial held by the holder in the chamber. A collection manifold is connected via tubing to the outlet means of each sample vial for collecting purified inert gas, such as Nitrogen, and gases from each sample vial connected to the distribution manifold. The chamber, distribution manifold and collection manifold coacting to expose a sample in each sample vial to only purified inert gas, such as Nitrogen, during the evaporation of the sample.

  • Patent number: 5193404
    Abstract: An apparatus is set forth for removing a sample of a liquid for chemical analysis from a vessel containing the liquid and for delivering the sample into a sample bottle. The apparatus comprises a hollow member defining an enclosed plenum. A sample bottle attachment structure defines a passage communicating with the plenum and being adapted for attachment to a top portion of the sample bottle. A first partition structure blocks off the passage other than where it communicates with the plenum. A longitudinally extending sample transport tube extends through the passage and into the bottle. The transport tube passes through the first partition in substantially air-tight relation to it. The other end of the transport tube is positionable in the liquid being sampled.

  • Patent number: 4930360
    Abstract: An apparatus and method are set forth for removing a sample of a liquid for chemical analysis from a vessel containing the liquid and for delivering the sample into a sample bottle. The apparatus comprises a hollow member defining an enclosed plenum. A sample bottle attachment structure defines a passage communicating with the plenum and being adapted for attachment to a top portion of the sample bottle. A longitudinally extending sample transport tube extends through the passage and into the bottle. The transport tube passes through the hollow member in substantially air-tight relation to it. The other end of the transport tube is positionable in the liquid being sampled. The method comprises positioning one end of a tube in a sample bottle and the other end in the liquid. A hand operated pump manually creates a partial vacuum in the bottle to draw the sample.
