A system and method for quantitative analysis of a solution to determine the concentration of a chemical species in the solution. The system includes a reaction vessel; a source of at least one liquid reagent for reacting with the chemical species being tested for; a conduit leading from the reagent source to the reaction vessel; pneumatic pressure for forcing the reagent through the conduit; controls for controlling the amount of reagent added to the reaction vessel; and a detection device for detecting reaction between the reagent and the chemical species.
