This high-purity potassium standard solution is formulated at a concentration of 1,000 micrograms per milliliter in 5 percent nitric acid, ensuring reliable and consistent performance in elemental analysis workflows. Designed specifically for use with atomic absorption (AA) spectroscopy and microwave plasma atomic emission spectroscopy (MP-AES), it serves as a calibration or quality control standard for precise quantitative determination of potassium in a wide array of sample matrices. The 500 milliliter format is ideal for routine laboratory analysis in environmental, food, agriculture, pharmaceutical, and clinical research settings. Each batch is manufactured in an ISO-certified facility, ensuring traceability to NIST standards for regulatory compliance and reproducibility. The solution is ready to use, eliminating preparation steps and minimizing contamination risk. It is compatible with all major AA and MP-AES spectrometers, including Agilent instrument platforms, and pairs seamlessly with multi-element standards for comprehensive calibration routines. Researchers can use this solution for instrument calibration, spike recovery experiments, or proficiency testing, supporting accurate results and robust quality assurance practices. For best performance, store the solution at room temperature and tightly capped when not in use. Related single- and multi-element calibration standards are also available to complete your laboratory’s analytical requirements.
