Significance of Calibration curve
A calibration curve is a graphical representation that establishes the relationship between the concentration of a substance and its corresponding absorbance values. It is utilized to determine the concentration of unknown samples by plotting absorbance against known concentrations. This method is essential in quantitative analysis as it correlates measured responses with known standards, allowing for effective determination of unknown concentrations across various substances, including drugs. The calibration curve thus serves as a fundamental tool in analytical chemistry.
