Potassium Standard Solution 1000 mg/L (1000 ppm) 100ml

SKU : I-9073.0100
CAS : 7757-79-1
Formula : K
Grade : standard solution

Potassium 1000 mg/L (1000 ppm) Standard Solution is primarily used as a precise reference for calibrating analytical instruments like Ion Chromatographs (IC), Atomic Absorption Spectrometers (AAS), and ICP-OES/MS to accurately measure potassium levels in environmental, food/beverage, pharmaceutical, and industrial quality control (QC) samples, ensuring reliability in detecting potassium in water, soil, products, and for conductometry.

Potassium Standard Solution of 1000 mg/L (or 1000 ppm) means there are 1000 milligrams (mg) of elemental potassium (K) dissolved in every liter (L) of solution, commonly prepared using potassium chloride (KCl) in water, serving as a precise, known concentration for calibrating analytical instruments like AAS (Atomic Absorption Spectrometry) or ICP (Inductively Coupled Plasma) for measuring potassium in samples.
  • 1000 mg/L (milligrams per liter): This specifies the concentration of the pure, elemental potassium (K⁺ ion) dissolved in the solution. This is a common unit for expressing trace element concentrations in liquids.
  • 1000 ppm (parts per million): This is another way to express the same concentration. For dilute aqueous solutions, 1 mg/L is approximately equal to 1 ppm, so these terms are often used interchangeably.
  • Traceability to NIST: These standards are often “traceable to Standard Reference Material (SRM) from NIST” (National Institute of Standards and Technology). This means the concentration has been rigorously verified against internationally recognized primary standards, ensuring high accuracy and reliability for professional use.
  • Preparation/Composition: The potassium is typically provided as a stable salt, like potassium nitrate (KNO3)  or potassium chloride (KCl), dissolved in a high-purity solvent (often deionized water or a dilute acid like 0.5 M nitric acid (HNO3).

Hello
Can we help you?
Labotiq focuses on a practical and precise field: laboratory supplies, chemical reagents, equipment, and plastic labware. This kind of work is all about accuracy, safety, and trust, because even small details can affect the final result. The same idea is becoming more relevant in digital entertainment, where choosing a platform also means paying attention to reliability, transparency, and user protection.Online entertainment has turned into an everyday habit, from streaming and mobile games to casino-style platforms and interactive services. Still, a good digital experience starts with clear rules, secure payments, licensed operators, and easy-to-understand information. Anyone interested in safe online leisure and the Spanish gambling market can find a useful reference in mejores casinos en España. The topic is not only about fun, but also about choosing platforms carefully, understanding how regulation works, and avoiding random decisions when money and personal data are involved.That creates a simple connection between the two areas. Labotiq supports laboratories with dependable products for controlled work, while trusted information about digital entertainment helps users feel more confident online. When reliability comes first, both laboratory processes and online services become easier to understand, safer to use, and more valuable in everyday life.
