cod vials for water analysis USA

Pre-filled with COD reagents, these digestion vials come in EPA-approved versions for low-, standard-, and ultra-high-range analysis. Each lot is tested to ensure superior quality from the cap and vial to the chemical contents. Glass vials are 16 mm x 100 mm to work with your existing COD reactor and spectrophotometer.

The COD test is used to predict the requirement an effluent will have for oxygen and hence the effluent's likely impact on the aquatic life of the receiving water course. COD can be measured in three ranges. LR (0-150 mg/l) is applicable for final effluents and treated waste water. MR (0-1500 mg/l) is suitable for measuring crude sewages, untreated and partially treated waste water.

Mar 17, 2021 · Mar 17 2021. CHEMetrics® offers two methods (USEPA-accepted and mercury-free) for the determination of COD levels in wastewater—at a much lower cost than competitive vials. Measuring chemical oxygen demand (COD) is one of the most frequently performed tests for assessing water quality. It is widely applied in municipal wastewater facilities

Depending on the composition of the water stream, there are a number of compounds that can interfere with COD testing when found in extremely high concentrations. Chromium, nitrite, sulfite, sodium nitrate, sodium sulfate, sodium phosphate, and chloride can all potentially impact accuracy when found in high enough concentrations.

A COD standard solution (100 mg/L) in water obtained from VWR was used to test the accuracy and precision of this method. An oven (or thermoreactor) was preheated to 148 oC. After removing the screw cap from a COD vial, 2.0 ml of the 100 mg/L COD standard was placed in the vial, the cap replaced, and the contents mixed vigorously.
