Description
SL K 70230 is a ready-to-use potassium standard solution with a concentration of 1000 mg/l supplied in a 500 ml pack. This reference preparation is designed for calibration, method validation and quality-control tasks in laboratories performing potassium determinations by photometric, ion-selective or other instrumental techniques. The defined concentration allows analysts to verify instrument linearity, check reagent performance and establish reliable measurement traces for water, wastewater or process samples. Available from manufacturer WTW - a Xylem brand, the solution supports routine analytical workflows where consistent potassium values are required. The 500 ml volume provides sufficient material for multiple calibration series or ongoing control samples without frequent reordering. Ready-to-use presentation eliminates preparation steps and reduces the risk of dilution errors. Laboratories engaged in environmental monitoring, industrial process control or research applications can incorporate the standard directly into existing protocols. Stable concentration characteristics help maintain long-term comparability of results across different instruments and operators. The product is delivered as a single unit suitable for immediate laboratory use.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about SL K 70230, Standard Solution Potassium 500 ml Concentration 1000 mg/
What is this article?
SL K 70230, Standard Solution Potassium 500 ml Concentration 1000 mg/ is the article on this page. Luminix Health distributes WTW - a Xylem brand 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.
