standardikäyrä
Standardikäyrä, also known as a calibration curve or standard curve, is a graph used in analytical chemistry and related fields to determine the concentration of an unknown analyte. It is created by plotting the known concentrations of a series of standard solutions against their corresponding measured responses, such as absorbance, fluorescence, or peak area in chromatography. The relationship between concentration and response is typically assumed to be linear within a certain range.
To construct a standardikäyrä, several solutions with accurately known concentrations of the substance of interest are
Once the standardikäyrä is established, the measured response of an unknown sample can be used to determine
