kalibratiereeks

A kalibratiereeks, or calibration series, is a fundamental concept in metrology and analytical chemistry. It refers to a set of known samples, called standards, that are prepared with precisely measured concentrations of the analyte of interest. These standards are then analyzed using the same method that will be used for the unknown samples. The results obtained from analyzing these standards are used to create a calibration curve or calibration graph. This curve plots the measured response of the instrument (e.g., absorbance, peak area) against the known concentrations of the standards.

The purpose of a kalibratiereeks is to establish a relationship between the instrument's signal and the concentration of the substance being measured. Once this relationship is established, the unknown samples can be analyzed, and their concentrations can be determined by interpolating their measured responses onto the calibration curve. A well-constructed kalibratiereeks is crucial for accurate quantitative analysis. The number of standards in the series, their concentration range, and the linearity of the resulting calibration curve are all important factors influencing the reliability of the results. Multiple measurements of each standard are often performed to improve precision and identify any outliers. The quality of the standards themselves, including their purity and accurate preparation, directly impacts the accuracy of the entire calibration process.
