Solar-distilled plant water that has gone through various levels of laboratory preparation to remove constituents that can interfere with subsequent tritium analysis. A 2-gram solid-phase extraction column was necessary and sufficient for accurate determination of tritium concentrations in water from test plants (creosote bush, Larrea tridenatata) -- from the Detecting Tritium in Plants Photo Gallery
