PCT No. PCT/SE95/00888 Sec. 371 Date Apr. 17, 1997 Sec. 102(e) Date Apr. 17, 1997 PCT Filed Jul. 28, 1995 PCT Pub. No. WO96/04401 PCT Pub. Date Feb. 15, 1996Methods 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.
