Chemical Structure
Description
Potassium sodium alloy 78:22 (CAS 11135-81-2), molecular formula KNa and molecular weight 62.09 g/mol, is a CATO reference standard with documented purity and traceability.
Potassium sodium alloy 78:22 (KNa) contains an inorganic composition. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
