Kalibrierungslösung

Kalibrierungslösung, often referred to as calibration solution or standard solution, is a substance of precisely known concentration used to calibrate measuring instruments. These solutions are fundamental in analytical chemistry and various scientific fields to ensure the accuracy and reliability of measurements. The known concentration of the kalibrierungslösung acts as a reference point against which the instrument's response is compared.

Common applications for kalibrierungslösungen include calibrating pH meters, spectrophotometers, chromatography systems, and titrators. For instance, a pH meter is calibrated using buffer solutions of known pH values. A spectrophotometer might be calibrated with solutions containing a specific concentration of a light-absorbing substance. The accuracy of the kalibrierungslösung is paramount; any error in its preparation or concentration will directly translate into measurement errors. Therefore, these solutions are typically prepared with high-purity reagents and meticulously controlled procedures. They are often commercially available with certificates of analysis that attest to their certified concentration and uncertainty. Regular calibration with appropriate kalibrierungslösungen is a standard practice in quality control and research to maintain traceable and valid results.
