This Test is suitable for short time COD at 160°C within 30 minutes.

In contrast to the conditions described in the ISO 15705, the short time COD is characterised by a higher digestion temperature and reduced reaction time. Therefore we recommend comparing the results of the short time COD from time to time with measurements made under the conditions of ISO 15705 (150 ± 5°C / 2h ± 10 min).

Benefits of NANOCOLORtube tests in comparison to ISO 6060:

The new ISO 15705 is based on the same chemical reaction as the established ISO 6060. The water contents are oxidized by sulfuric acid and potassium dichromate in the presence of silver sulfate and mercury(II) sulfate. Compared with the ISO 6060, the new method, described in the ISO 15705 has significant advantages:

€¢ Five times less mercury

€¢ Comparably less other toxic and hazardous reagents

€¢ All reagents are pre-dosed in round tubes

€¢ Reduced risks for the user

€¢ Reproducible results because of photometric determination

If the chloride content exceeds 1500 mg/L the sample has to be diluted with COD-free water, or you may use the chloride complexing agent. Lower chloride concentrations are masked by the mercury(II) sulfate present in the test tubes.

Please note COD accessories:

Chloride complexing agent REF 918 911

for COD determinations with chloride concentrations from 1000€“7000 mg/L Cl€“

Sufficient for: 100-200 tests
Shelf life: at least 1.5 years

Cartridges for chloride elimination REF 963 911

for removal of up to 2000 mg/L Cl€“ per cartridge

Pack of: 10 cartridges
Shelf life: at least 1 year at 2€“8 °C

COD-free water REF 918 993

for control of measurements and dilution of water samples
