Abstract
The invention is directed toward apparatus and methods for gathering and preparing liquid samples for analysis for elements or compounds within the liquid samples. Although applicable to a variety of liquids and to a variety of elements or compounds, the preferred embodiment of the invention is directed toward the gathering and pretreating of water samples for tritium analysis. This disclosure is further directed toward apparatus and methods for the gathering or collecting of water samples from underground formations penetrated by a borehole, or collecting water samples at varying depths in surface canals, ponds, and the like. The invention is particularly suited for monitoring water in the vicinity of nuclear manufacturing, fabrication and disposal facilities for tritium contamination of ground waters.
