The HI93754J-25 are reagent vials that follow the EPA approved method for the ultra-high range determination of chemical oxygen demand (COD) using a compatible benchtop photometer. These high-quality reagents are clearly marked with the lot number and expiration date on each box for traceability.
The HI93754J-25 COD kit contains 25 ready-to-use vials containing pre-measured reagents. These high-quality reagents follow the EPA approved method 410.4. In this method, a heated digestion is required to oxidize organic matter in the sample.
Hanna vials contain approximately 3 mL of pre-dosed reagent so the user only needs to add a small quantity of the sample. With pre-dosed vials, test preparation time is dramatically reduced since there is no reagent preparation procedure. The vials and caps of the COD reagents have been designed to avoid accidental reagent spills.
Mercury-free – For those who do not wish to handle mercury reagents, our “green, ” mercury-free reagents are available for COD determination. These reagents are more sensitive to chloride interferences, as mercuric sulfate is not present. While the mercury-free reagents are easier to dispose of, they may be unacceptable for reporting purposes.
ISO – The ISO approved method 15705 for COD determination also requires the use of mercuric sulfate (HgSO4) to reduce the interference of chloride. Containing similar chemical reagents as the EPA method, it is important to treat used ISO vials as hazardous waste, as mercury waste requires recycling.
