This high-purity potassium buffer solution is designed to support a range of analytical applications requiring consistent and reliable potassium calibration. Prepared at a concentration of 100,000 micrograms per milliliter in 2 to 5 percent nitric acid, it ensures stability and homogeneity for precise elemental analysis. The formulation is ideally suited for use in atomic absorption spectroscopy, inductively coupled plasma optical emission spectrometry, and inductively coupled plasma mass spectrometry workflows, providing accurate calibration and quality control in routine and research laboratories. Supplied in a 500 milliliter bottle, the solution minimizes the risk of contamination, facilitating consistent performance and reproducibility in trace metal analysis. The buffer is fully compatible with Agilent’s suite of spectroscopy instruments and sample introduction systems, and also integrates seamlessly with most industry-standard analytical platforms. It is recommended for use in environmental studies, clinical research, food and beverage testing, and materials science when robust potassium quantification is required. Rigorous manufacturing and quality assurance procedures ensure traceability and compliance with laboratory standards. For specialized applications or broader multi-element analysis, this buffer can be used in conjunction with Agilent’s extensive range of single- and multi-element calibration solutions.
