This high-purity analytical standard solution contains potassium at a concentration of 1,000 micrograms per milliliter in a matrix of 5 percent nitric acid. The 100 mL volume is specifically designed for laboratories performing trace elemental analysis, allowing precise calibration and quantification of potassium in a variety of sample matrices. It is ideal for use in atomic absorption spectroscopy (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), and inductively coupled plasma mass spectrometry (ICP-MS), ensuring accurate and reliable results in both routine and research-driven analyses. Common applications include environmental testing, food and beverage quality control, clinical diagnostics, and pharmaceutical research. This standard is prepared under rigorous quality specifications to guarantee stability and compatibility with Agilent analytical systems, including the 200, 240, and 5100 Series ICP-OES instruments, 7700 and 7900 Series ICP-MS systems, and AA spectrometers. It is also suitable for method development, instrument calibration, and performance verification in laboratories that demand traceable and reproducible potassium measurements. For multi-element analysis, it is compatible with other Agilent single- and multi-element standards. Each bottle includes a Certificate of Analysis to document traceability and quality assurance, supporting critical laboratory workflows and regulatory compliance.
