Description
TOC Standard ROTI®Calipure 5000 mg/l is a calibration solution for total organic carbon (TOC) determination, prepared as potassium hydrogen phthalate. The standard is filled at 5000 mg/l in a 100 ml glass pack with a weight of 0,200 kg. Density (D) is approximately 1 g/cm³ and the boiling point (bp) is 100 °C, values that match an aqueous potassium hydrogen phthalate matrix. In the analytical laboratory, TOC standards of this type are used to calibrate or verify TOC analysers and related organic-carbon methods at a defined concentration. The 5000 mg/l level provides a stated reference for instrument setup and for preparing further working solutions according to internal laboratory procedures. Glass packaging at 100 ml is practical for routine calibration benches and limits handling of larger volumes. The product is part of the ROTI®Calipure range from manufacturer Carl ROTH. Potassium hydrogen phthalate is the chemical form given for the organic carbon content. This TOC Standard is intended for professional laboratory calibration where a 5000 mg/l solution in glass is specified.
This article is part of Reagents for analysis (Ph. Eur., ASTM, DIN), in Analytical standards & reference materials.

Questions about TOC Standard ROTI®Calipure 5000 mg/l, 100 ml, glass
What is this article?
TOC Standard ROTI®Calipure 5000 mg/l, 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.
