Måleprøver

Måleprøver, often translated as "measuring samples" or "calibration samples," are materials of known composition or properties used in analytical chemistry and various scientific disciplines. Their primary purpose is to establish a reference point for calibrating instruments or validating analytical methods. By analyzing a måleprøve with a known concentration of a specific substance, an instrument's response can be correlated to that known concentration. This allows for accurate quantification of unknown samples.

These samples are crucial for ensuring the reliability and accuracy of measurements. They can be used in a wide range of applications, from environmental monitoring to pharmaceutical quality control. For instance, in water analysis, a måleprøve containing a known amount of a pollutant would be used to calibrate the instrument that detects that pollutant in actual water samples. Similarly, in clinical diagnostics, reference materials with known levels of biomarkers help ensure accurate patient test results.

The preparation and certification of måleprøver are typically carried out under strict quality control protocols. The accuracy of the assigned values for these samples is paramount, as any error in the måleprøve will directly lead to errors in subsequent measurements. They can be pure substances, mixtures, or even matrices that mimic the sample being analyzed. The concept of a måleprøve is fundamental to quantitative analysis, providing the necessary link between instrumental signal and real-world concentration.
