The Rosemount Analytical online wet-chemistry analyzers for sodium (photo), silica, phosphate, hydrazine and ammonia are used for process monitoring in the power and ultrapure water industries. The analyzers are easy to use. Pressing one button starts, calibrates and puts the instrument online. Routine reagent replacement and maintenance takes only 5 min every three months, and replacing the valve pump — the heart of the analyzer — takes about 15 min every two years. The addition of wet chemistry analyzers (acquired from Scientific Instruments Inc. in May 2009) complements this firm’s line of conductivity, pH and dissolved oxygen sensors and analyzers. — Emerson Process Management, Baar, Switzerland
