This high-purity potassium standard solution offers a concentration of 1,000 micrograms per milliliter in 5 percent nitric acid, ensuring accuracy and consistency in calibration procedures. Specially formulated for use in atomic absorption spectroscopy and microwave plasma atomic emission spectrometry, this reference material enables precise quantification of potassium in diverse matrices. The stable chemical composition minimizes contamination risk and guarantees reliable, reproducible results essential for laboratories conducting elemental analysis in environmental, clinical, food, pharmaceutical, or industrial testing. Supplied in a 100 milliliter container, it is ideal for laboratories with moderate sample throughput.

This solution is manufactured under stringent quality controls to meet the exacting requirements of modern analytical workflows. It is compatible with Agilent AA and MP-AES instrumentation, and can also support other major instrument brands where potassium calibration is required. Suitable for use in method development, quality control, instrument performance verification, and proficiency testing, this ready-to-use solution reduces preparation time and potential dilution errors. For comprehensive multielement analysis, it may be used in conjunction with certified standards for other alkali metal or trace element measurements. Reliable and convenient, this standard supports precise determinations in research, regulatory compliance, and routine laboratory practices.
