COD Cell Tests where customers can measure COD in samples of seawater or unlimited chloride levels.
COD is a very important parameter in water and waste water analysis but could not be measured by photometry in samples with high chloride contents. Dilution often is not possible because of the low value of COD.
The chloride interferences will be removed by depleted by means of sulfuric acid and an HCl absorber. The resultant prepared sample will be add to the new developed COD tube with a special sulfuric acid water mixture to keep the sulfuric acid water ratio according to the norms.
Applications: Seawater, coastal and marine water, brackish water, industrial waste water, ground water with high chloride levels, cooling & boiler water.
