Food processing engineers responsible for rinsing, washing and disinfecting fruits, vegetables and other disinfecting processes will find the new plug-n-play FC80 High Range Free Chlorine Analyzer from Electro-Chemical Devices (ECD simplifies water-based disinfection while installing easily and requiring less maintenance for lower total cost-of-ownership. The highly reliable FC80 High Range Free Chlorine Analyzer monitors free Chlorine in produce disinfection supply water, cleaning and disinfection of water supply lines, and cleaning solution water samples from 0.05 200 ppm Chlorine (Cl2 . The FC80 is ideal for the monitoring Cl2 levels in disinfection processes to help ensure the elimination of disease-causing pathogens including E. coli, Cyclospora, Salmonella and Hepatitis. High concentration Cl2 disinfection is utilized in a variety of food processing operations and produce packing lines. All of these Cl2 disinfection techniques, however, require the introduction of liquid or solid Cl2 into water tanks that are connected to washer or spray line systems. According to the U.S. Food & Drug Administration (FDA , liquid chlorine and hypochlorites are generally used in the 50 to 200 ppm concentration range with a contact time of 1 to 2 minutes to sanitize produce surfaces and processing equipment. Hypochlorous acid (HOCl is the form of freely available chlorine that has the highest bactericidal activity against a broad range of microorganisms. The FDA states that in water-based solutions, that the equilibrium between hypochlorous acid (HOCl and the hypochlorite ion (OCl is pH dependent with the concentration of HOCl increasing as pH decreases.
