Quickly invert Just about every vial ten periods while Keeping the vial because of the cap only as being the vial will probably be scorching within the reaction prompted when incorporating the sample.
Inspite of its prevalent use, there are several issues linked to COD measurement. On the list of major troubles is using hazardous chemicals inside the measurement procedure.
Be sure that the reagent blank vial is similar whole lot number as being the test vials. Be aware: At the least one reagent blank need to be operate with Every list of samples with Each and every new great deal amount of COD test vials.
Insert the COD reagent blank into the sample compartment and press the Zero/Test vital. The “cod” image will flash for roughly 8 seconds.
This technique is fairly straightforward and provides A fast and accurate evaluate of COD. On the other hand, it has some disadvantages, such as the usage of dangerous chemicals and The lack to differentiate concerning biologically out there and inert natural make a difference.
