[. . . ] Instruction Manual Method Reagents are in accordance with ISO 15705:2002 method. This method covers the determination of COD in surface water, domestic and industrial wastes. [. . . ] For colorimetric determination of COD, follow the procedure described in the Photometer Instruction Manual*. * Note: for best results in readings use the Hanna equipment: C9800 Reactor and C99 or C214 Photometers. INTERFERENCES: chlorides >1000 mg/L (ppm) Samples with higher chloride concentration should be diluted. COD Chemical Oxygen Demand ISO Reagents Instructions Before starting to use these reagent kits it is important to read carefully this manual and the Health & Safety Data Sheet (HSDS). For sample digestion use a block heater reactor with holes to accommodate digestion vials. Do not use an oven or microwave because leaking samples can generate a corrosive and possibly explosive atmosphere. Note: the reagent is light sensitive, thus store the unused vials in their container and in a refrigerator if possible. Using a Class A glass pipette, add 2 ml of sample to a HI 93754F-25 vial for low range or to a HI 93754G-25 vial for medium range, while keeping the vial at a 45degree angle. sample www. hannainst. com Dear Customer, Thank you for choosing a Hanna product.
