Excessive metal content can contribute to corrosion in the piping used in the cooling systems in power stations. As a part of corrosion management in power plant cooling systems, the chemistry of cooling water is routinely monitored for unwanted metals using both Millipore and Cation filters. The filters are then analyzed to determine concentrations of iron (Fe) and copper (Cu), as well as other unwanted metals such as nickel (Ni), zinc (Zn), and lead (Pb). Featuring an offset spinner for a maximum surface area coverage of large filters, Applied Rigaku Technologies, Inc. offers the NEX DE EDXRF analyzer to meet these analytical demands.
