Notes:
1. Run samples and blanks with the same batch of vials. The blank is stable when stored in
the dark and can be used for further measurements with vials of the same batch.
2. Do not place the hot vials in the sample chamber. Cool the vials to room temperature for
final measurements.
3. Suspended solids in the vial lead to incorrect measurements. For this reason it is impor-
tant to place the vials carefully in the sample chamber. The precipitate at the bottom of
the sample should be not suspended.
4. Clean the outside of the vials with a towel. Finger prints or other marks will be removed.
5. Samples can be measured when the Chloride content does not exceed 10 000 mg/l.
6. In exceptional cases, compounds contained in the water cannot be oxidized adequately,
so results may be lower than reference methods.
7. For samples under 1 g/l COD it is recommended to repeat the test with the test kit for
COD MR or for samples under 0,1 g/l COD with the tube test COD LR.
