There are vials for 25 tests to be used with Hanna’s HI801 and HI802 spectrophotometers as well as HI83399 and HI83314 COD photometers. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date for traceability. The method used is an adaptation of Mercury Thiocyanate Method. One of the key advantages of this method is the reagent formulation, which is free from methanol. This ensures greater operator safety compared to alternative methods, as it reduces exposure to toxic substances during testing. Each reagent box is supplied with Certi cate of Analysis. An important advantage of the HI96793-25 and HI96794-25 is that they can be stored at room temperature, avoiding the inconvenience of having to store them in the refrigerator, saving lab space and simplifying handling. Unlike competitor vials, Hanna reagents are always ready to use, eliminating waiting time to reach room temperature and making analyses faster and more e´cient. Furthermore, the reagents have a shelf life of two years. The procedure involves the use of 13 mm (internal diameter) cuvettes, with a longer optical path than many other vials on the market. This ensures accurate absorbance measurements and greater repeatability of results. Signi cance and Use Chloride analysis is essential for evaluating water quality and ensuring compliance with discharge regulations. In wastewater, chloride concentration is strictly regulated in every country, as excessive levels can harm aquatic ecosystems and aect downstream water use. Industrial eÇuents often contain chlorides due to the use of ferric or aluminum polychloride as coagulants during treatment. In addition, chlorides are known to interfere with the measurement of key parameters such as Chemical Oxygen Demand (COD), making their accurate determination crucial for reliable water quality monitoring. Regular testing supports compliance, process optimization, and environmental protection. Application Chloride determination in wastewater, industrial eÇuents, groundwater, surface water, and drinking water. 9 Reasons to Choose Hanna 1.
