Abstract: Organic water conditioning agents may be added to an aqueous stream that is supplied to a steam generator, such as a heat recovery steam generator within a combined cycle power plant. These organic water conditioning agents may degrade to electrically-charged decomposition products that can interfere with cation conductivity measurements made on the aqueous stream. To allow deployment of the organic water conditioning agents, a sampling device can process aqueous samples to destroy interfering organic molecules, such as through heat or irradiation. Cation conductivity measurements can then be made on the aqueous sample after destroying and removing interfering organic species from the sample stream.
