Description
COD Standard 500 ppm, 500 ml is a chemical oxygen demand reference solution supplied at a concentration of 500 ppm in a 500 ml pack. Offered as 1 pc, it provides a defined standard for calibration, verification, or quality-control checks in COD photometric and related spectroscopic workflows. Net weight is 0,57 kg and gross weight is 1,57 kg, keeping the bottle practical for laboratory handling and storage. This COD standard from manufacturer Hanna Instruments is produced in Romania and sits within the spectroscopy accessories range used for water and wastewater analysis. Laboratories that run chemical oxygen demand methods can use the 500 ppm level to support instrument checks and method consistency across analytical batches. The liquid format allows straightforward dosing into cuvettes or preparation vessels according to the laboratory’s established COD procedure. Clear concentration labelling at 500 ppm helps operators select the correct standard for the intended measuring range. The product is suited to environmental, industrial, and municipal laboratories that maintain COD photometry as part of routine monitoring programmes.
This article is part of Reagents for analysis (Ph. Eur., ASTM, DIN), in Analytical standards & reference materials.

Questions about COD standard 500 ppm, 500 mL, regular bottle
What is this article?
COD standard 500 ppm, 500 mL, regular bottle is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in Reagents for analysis (Ph. Eur., ASTM, DIN), inside Analytical standards & reference materials, in Lab chemicals.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
