Description
Potassium ISE standard solution, 1000 mg/L, is a ready-to-use calibration standard for ion-selective electrode (ISE) measurement of potassium. At a defined concentration of 1000 mg/L it supports calibration, verification and performance checks of potassium-selective sensors in everyday laboratory practice. The solution is supplied in a 500 ml pack with a net weight of 0,58 kg, making it convenient for routine QC, method validation and multi-point calibration sequences. This standard from manufacturer Mettler-Toledo OnLine helps laboratories maintain consistent reference levels when building calibration curves or monitoring electrode slope and response over time. A prepared ISE standard limits variability associated with manual stock preparation and supports reproducible potassium determinations across instruments and operators. The 1000 mg/L concentration is suitable as a high-range calibration point or for preparing intermediate working standards according to laboratory procedures. It fits electroanalytical applications in research, process monitoring and water or environmental testing environments. Provided as one piece per unit and originating from Ireland, the product is a practical addition to laboratory material stocks for potassium ISE analysis.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about ISE standard K 1000 mg/L, 500mL
What is this article?
ISE standard K 1000 mg/L, 500mL is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
Which category should I open next?
