Hana COD reagent HI93754

HanaCODreagentHI93754

HI93754typeCODReagents from25Composed of customized glass reagent tubes containing pre made reagents, these high-quality pre made reagents meet the requirements ofEPAstandard410.4Method, dichromate, mercury free andISOStandard standards15705method;

Before use, it is necessary to useHI839800Heating and digestion device settings150ºC(302ºF)Perform a two-hour heating pretreatment [Do not use an oven or microwave as it may cause corrosion or explosion];

During the digestion heating process, hexavalent chromium in the pre prepared reagent is reduced to trivalent chromium.

After the digestion and heating treatment is completed, be careful to move the heating test tube toHI740216Cooling on stainless steel test tube cooling rack for approximately20More than minutes to room temperature, Then useHI801TheHI83399orHI83314 CODThe photometer is used for colorimetric measurement of the amount of reduced chromium, that isCODConcentration tomg/L(ppm)O2Display the reading.

comply withEPAstandard410.4methodCODReagent, containing mercuric sulfate（Hgso 4）To reduce the interference of high chloride content on measurement results, suitable for the wastewater and food industriesCODConcentration measurement
