The GB/T 26812-2011 standard specifies the preparatory method for calibrating solutions for Ion selective electrodes, including the required reagents, equipment and steps. The standard applies to the preparation of calibrated solutions for sodium ions, chloride ions, fluoride ions, nitrate ions and ammonia Gas sensing electrodes, as well as calibrated solutions for related ion meters. The standard details six different solutions and their composition concentrations, and specifies the purity and water quality requirements for reagents such as sodium chloride, sodium fluoride, etc. This standard aims to ensure the accuracy and Reliability of calibrated solutions to improve the Accuracy of electrode measurements.
