10mL cod digestion vials on stock

COD digestion reagent vials, multiply the result by 10. For the most accurate results with samples near 1500 or 15,000 mg/L COD, repeat the analysis with a diluted sample. Blanks for colorimetric determination The blank vial can be used again and again for measurements that use the same lot of reagent vials.

COD concentration increases. The low range COD digestion is read at 420 nm and is proportional to the decrease in the dichromate ion (Cr 2 O 7 2-), which causes the solution to move towards a colorless/pale blue shade as the COD concentration increases. Your digested zero COD standard will have a higher absorbance than your digested 100 mg/L
