Welcome to the “Analytical Standards Excellence Circle,” a group dedicated to the exploration and discussion of analytical standards in quantitative analysis. Analytical standards are compounds of high purity and known concentration used to confirm the presence of specific components in mixtures, enhance precision, and calibrate analyzers. With their characteristic values providing good accuracy and compatibility with SI units, these standards are critical in achieving consistent and reliable results. Join us to exchange insights and knowledge on the global determination and application of these essential reagents.
