TOC Standard ROTI®Calipure 400 mg/l is a ready-to-use calibration solution prepared as potassium hydrogen phthalate for total organic carbon determination. Offered in a 100 ml glass bottle, it provides a defined 400 mg/l concentration level for instrument calibration, system suitability checks, and routine quality control in water, environmental, and process laboratories. Physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with an aqueous preparation that integrates smoothly into standard TOC workflows. Analysts use fixed concentration standards of this type to build or verify calibration curves, confirm detector response, and support method validation across a range of sample matrices. The ROTI®Calipure grade from manufacturer Carl ROTH is intended for analytical calibration practice where reproducible organic carbon content is required. The compact 100 ml pack size suits single-point checks as well as multi-level series when combined with other concentration variants, helping laboratories maintain reliable TOC measurement performance day to day.

Questions about TOC Standard ROTI®Calipure 400 mg/l, 100 ml
What is this article?
TOC Standard ROTI®Calipure 400 mg/l, 100 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reagentia voor analyse (Ph. Eur., ASTM, DIN), inside Analytische standaarden & referentiematerialen, in Chemicaliën.
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.
Which category should I open next?
The category is Analytische standaarden & referentiematerialen. The sub-category is Reagentia voor analyse (Ph. Eur., ASTM, DIN). The catalogue is Chemicaliën.
