COD Cell Test for seawater / high chloride contents

Descrição detalhada : Method: photometric 5.0 - 60.0 mg/l Spectroquant(R) The chloride content of the water sample is depleted by means of sulfuric acid and an HCl absorber. The water sample is subsequently oxidized with a hot sulfuric solution of potassium dichromate, with silver sulfate as the catalyst. Residual chloride is masked with mercury sulfate. The concentration of green Cr3+ ions is then determined photometrically. The chloride depletion method corresponds to DIN 38409-41-2.The method corresponds to DIN ISO 15705 and is analogous to EPA 410.4, APHA 5220 D, and ASTM D1252-06 B.The Spectroquant(R)Cell Tests come with prefilled 16 mm round cells and all the required reagents to perform the analysis according to the instruction leaflet provided. All Spectroquant(R) Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) , which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
