Application Note

Potassium carbonate is a high-purity inorganic base supplied in EMSURE® grade for analytical and regulated laboratory applications. This 1 kg pack corresponds to ACS, ISO and Reag. Ph Eur requirements and has an assay of at least 99.0% by acidimetric determination. K₂CO₃ is useful where a soluble alkaline carbonate is required for reagent preparation, pH adjustment, analytical chemistry or controlled reaction conditions. The specification includes limits for insoluble matter, chloride, phosphate, silicate, sulfur, nitrogen and trace metals, helping reduce interference in quantitative work. Its defined reagent quality makes it suitable for laboratories that need consistent carbonate concentration and impurity control rather than technical-grade material.
