Referansenormer
Referansenormer, or reference standards, are materials of known identity and purity used in analytical chemistry and related fields for calibration, validation, and quality control. They serve as benchmarks against which unknown samples are compared to determine their identity, quantity, or quality. These standards are typically produced and certified by accredited organizations or manufacturers and come with a certificate of analysis detailing their properties and purity.
The use of referansenormer is crucial for ensuring the accuracy, reliability, and comparability of analytical results
Referansenormer can be categorized into primary, secondary, and working standards. Primary standards are of the highest
