Description
TOC Standard ROTI®Calipure 45 mg/l is a calibration solution for total organic carbon (TOC) determination, prepared as potassium hydrogen phthalate at 45 mg/l. Packed as 100 ml in glass, it has a density of approximately 1 g/cm³ and a boiling point of 100 °C, values that match an aqueous potassium hydrogen phthalate standard. The 45 mg/l ROTI®Calipure grade supplies a defined carbon concentration for laboratory TOC analysers and method checks that specify this level. Physical handling is guided by the density of ~1 g/cm³ and the boiling point of 100 °C, which indicate a water-based liquid under ordinary laboratory conditions. This TOC Standard from manufacturer Carl ROTH is therefore a potassium hydrogen phthalate solution in a 100 ml glass pack, intended for calibration tasks where a 45 mg/l TOC reference is required. Analysts can use the ROTI®Calipure 45 mg/l potassium hydrogen phthalate solution as a TOC Standard in routine calibration of carbon analysers that require a 45 mg/l reference in a 100 ml glass format.
This article is part of Reagents for analysis (Ph. Eur., ASTM, DIN), in Analytical standards & reference materials.

Questions about TOC Standard ROTI®Calipure 45 mg/l, 100 ml, glass
What is this article?
TOC Standard ROTI®Calipure 45 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.
