Description
Potassium sulphate solution ROTI®Star 100 mg/l K₂SO₄ in H₂O is an aqueous laboratory solution containing potassium sulphate at a defined concentration of 100 mg/l in water. It is prepared from the inorganic salt with empirical formula K₂SO₄, CAS number 7778-80-5 and EG nr. 231-915-5. Stated physical data include a molar mass of 174,27 g/mol, a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with a dilute aqueous matrix. The solution is Analytical and quality-control laboratories use such standards for calibration, verification and routine measurements that require a known level of potassium sulphate. The ready-to-use format reduces preparation steps when protocols specify 100 mg/l K₂SO₄ in H₂O. Research, environmental and industrial laboratories can apply the solution within instrumental methods and wet-chemical procedures that call for this concentration. Handling follows normal laboratory practice for aqueous inorganic standards, with the HDPE container supporting secure storage and dispensing during daily analytical work.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Potassium sulphate solution, ROTI®Star 100 mg/l K2SO4 in H2O, 100 ml, HDPE
What is this article?
Potassium sulphate solution, ROTI®Star 100 mg/l K2SO4 in H2O, 100 ml, HDPE is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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.
