High range, chemical oxygen demand determinations: COD Digestion Vials, High Range Chemical Oxygen Demand (COD): US EPA approved for wastewater analysis using Hach Method 8000 Method: Reactor Digestion Range: 20 -1500 mg/L COD 25/test
Chemical oxygen demand (COD) is the measurement of oxygen required to chemically oxidize organic substances in water. Therefore, COD evaluates water and wastewater quality. The COD test is carried out in the presence of a strong oxidant under acidic conditions.
The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency. This test is based on the fact that a strong oxidizing agent, under acidic conditions, can fully oxidize almost any organic compound to

Description. The Milli-Q™ IX 70010 has been designed in a compact, ergonomic, mercury-free and intelligent way to deliver high quality pure water. The system features three separate and distinct components: Milli-Q™ production unit offers flexible installation and a more simplified maintenance. The Milli-Q™ IQ Storage Tank and Top Tank is
Biochemical oxygen demand, or BOD, is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a
The determination of chemical oxygen demand (COD) index was also developed to measure carbohydrates especially in standard assays of wastewater quality
14/10/2005 · An optical biosensor for parallel multi-sample determination of biochemical oxygen demand (BOD) in wastewater samples has been developed. The biosensor monitors the dissolved oxygen (DO) concentration in water through an oxygen sensing film immobilized on the bottom of glass sample vials.
