The HI94754A-25 are barcode reagent vials that follow the EPA approved method for the low 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 Barcoded
2019/09/18 · The samples then cool and the samples are tested using a spectrophotometer. The chemical oxygen demand value will be read in mg/L for both total COD (tCOD) and soluble COD (sCOD). For samples with a concentration of 0 to 150 mg/L, use the low range COD vials. For higher concentrations the high range COD vials (0-1500 mg/L) should be used.
2008/08/21 · Accu-TEST® from QM Environmental Services Ltd offers a competitive alternative to currently available COD test kits on the market.The EPA accepted Accu-TEST Micro-COD System offers fast, low-cost determination of chemical oxygen demand (COD).
Pre-prepared low-range (3 - 150 ppm) or high-range (20 - 1500 ppm) vials are selected for the COD test based on expected results. Both ranges can be used if expected results are unknown.
Chemical concentrations in such waste are typically low enough to be accepted by a local treatment works. OSHA recommends that a separate sink be used exclusively for disposal of human blood, body fluids, and infectious
A low background double-tilt holder for chemical analysis by EDS, a standard double tilt holder, a heating holder capable of 1000C, and a heating straining holder are available. Probes as small as 1 nm in diameter are accessible

ISO 9001:2015 Certified accu-Test tm Micro Chemical Oxygen Demand System The Micro-COD Test Method - Accu-Test Mercury-Free Vials, Spectrophotometric Method Scope and Application 1.1 The Chemical Oxygen
The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater. The contamination level is determined by measuring the amount of oxidant required to oxidise the organic matter in the sample. This is equivalent to amount of oxygen that
