Abstract
Methods and apparatus for measuring the concentration of decomposable substances, such as urea, are disclosed. The disclosed methods include adding a gaseous buffer, such as CO2, to the solution containing the decomposable compound, measuring the conductivity of the solution, decomposing the decomposable compound, measuring the conductivity of the thus-decomposed compound solution, and calculating the differential conductivities between the two measured solutions. The apparatus for carrying out these methods are also disclosed.
Claims19
Apparatus for measuring the concentration of a decomposable compound in a solution comprising charging means for charging a buffer in gaseous form to said solution, a reactor for decomposing said decomposable compound whereby a reacted solution is formed, and measuring means for measuring the conductivities of said solution and said reacted solution whereby a differential conductivity can be calculated therefrom.
