New Line of Wet Chemistry Analysers Introduced

Emerson Process Management (UK) announces the first shipment of Rosemount® Analytical on-line wet chemistry analysers for sodium, silica, phosphate, hydrazine, and ammonia. The analysers are used for process monitoring in the power and ultrapure water industries.

The addition of wet chemistry analysers expands Emerson’s industry-leading line of conductivity, pH, and dissolved oxygen analysers and sensors. The wet chemistry line, originally developed by Scientific Instruments Inc., which Emerson acquired in May 2009, was already well-established in the power and semiconductor industries.

The analysers are easy to use. Pressing one button starts, calibrates, and puts the instrument on-line. Routine reagent replacement and maintenance takes only five minutes every three months. Replacing the valve pump, the heart of the analyser, requires about 15 minutes every two years. Reagents are ready-to-use; there are no messy chemical solutions to prepare and standardise. The analyser features self-diagnostics that validate the accuracy of the measurement by monitoring critical functions and alerting the user when a problem occurs, such as a leak, low reagent, or an out-of-range measurement. The analyser can measure as many as six sample streams sequentially.
