Description
COD Standard ROTI®Calipure 400 mg O2/l in H2O is an aqueous calibration standard intended for chemical oxygen demand (COD) analysis. Prepared at a defined level of 400 mg O2/l, the solution supports calibration, verification and quality control of COD methods used in environmental monitoring, wastewater testing and industrial process control. It is Physical characteristics include a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with an aqueous matrix. Laboratories select discrete COD concentration points such as this when building multi-point calibration curves or when checking instrument response at a specific oxygen-demand level. The product belongs to the ROTI®Calipure range from manufacturer Carl ROTH and is designed for routine analytical workflows that require reliable reference values. Combining this 400 mg O2/l standard with other concentrations in the same series enables flexible calibration strategies across the working range of common COD photometers and titration systems.

Questions about COD Standard, ROTI®Calipure 400 mg O2/l in H2O, 100 ml, glass
What is this article?
COD Standard, ROTI®Calipure 400 mg O2/l in H2O, 100 ml, glass is the article on this page. Luminix Health distributes Carl Roth 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.
