Abstract

The liquid sample take-up device comprises two layers ofconcentric tubing. An outer tube has a fluid take-up end forselective immersion in a liquid to be sampled, and a liquid connection spaced from the fluid take-up end adapted to receive a chemical reagent under pressure, creating a reagentflow toward the take-up end. An inner tube is disposed within the outer tube and has an open end adjacent to theouter tube take-up end. The inner tube is adapted to fluid connect to a negative pressure source, higher than the reagent pressure, to create a fluid flow within the innertube in a direction away from the open end, whereby sampledliquid and reagent are mixed adjacent the inner tube open endand within the outer tube take-up end. When the outer tubetake-up end is not immersed in a liquid to be sampled, airis drawn into the outer tube take-up end and into the innertube open end, creating a series of air bubbles, each bubbleseparated by a volume of reagent.
