Abstract
An apparatus for determining the quantitative presence of ions derived from solids, liquids, gases or similar items in which a deionized liquid dissolves the ions from the items, the liquid then is evaluated for conductivity by virtue of the presence of the ions, the liquid is then passed through a deionizer to substantially remove the ions, and again the liquid is re-exposed to the partially cleansed item; the cycle is continued until conductivity indicates that a predetermined degree of deionization has been achieved.
