The HI93754 COD High Range Reagent Vials, Dichromate Method (25 tests) are reagent vials that follow the dichromate method for the high range determination of chemical oxygen demand (COD) using a compatible benchtop photometer. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each box for traceability.

Pre-dosed reagents for ease of use
Supplied with certificate of quality
Marked with expiration date and lot number for traceability

Hanna vials berisi sekitar 3 mL reagent, sehingga user hanya perlu menambahkan sedikit ke dalam sample. With pre-dosed vials, test preparation time is dramatically reduced and there is no time-consuming reagent preparation procedure or glassware cleaning. Kami merancang wadah vial dengan tutup khusus sehingga mencegah tumpah yang tidak sengaja. Due to the pre-dosed reagents, the amount of chemicals and handling time is also minimized.

Comparison of Methods

EPA– The EPA approved method 410.4 for COD determination requires the use of mercuric sulfate (HgSO₄). Mercuric sulfate is present in the EPA reagent vials to mitigate the interference of chloride in the measurement sample. This is a common requirement for wastewater treatment plants and food manufacturing facilities which tend to have higher concentrations of chloride present in their effluent. When using reagents that follow the EPA method, it is important to treat used vials as hazardous waste, as mercury waste requires recycling.

ISO– The ISO approved method 15705 for COD determination also requires the use of mercuric sulfate (HgSO₄) to reduce the interference of chloride. Containing similar chemical reagents as the EPA method, it is important to treat used ISO vials as hazardous waste, as mercury waste requires recycling.
