Significance of Calibration graph
A calibration graph is a vital tool in analytical chemistry, serving as a graphical representation that depicts the relationship between concentration and the measured response of analytes. It is plotted over a concentration range to illustrate how absorbance correlates with concentration across various substances, thereby facilitating the quantification of unknown samples. Calibration graphs confirm linearity in methods used for analyzing drugs, enhancing accuracy and reliability in determining substance concentrations through established relationships between known concentrations and their responses.

The concept of Calibration graph in scientific sources
The Calibration graph is a crucial tool that visually correlates substance concentration with peak area or absorbance, aiding in quantifying compounds like Atorvastatin in various solutions through comparative analysis.
(1) A calibration graph is a plot used in potentiometry to establish a relationship between the measured potential of the sensor and the concentration of the target ion, facilitating quantitative analysis.[1] (2) Graphs used to plot absorbance against concentration for the purpose of determining the concentration of unknown samples.[2] (3) A graphical representation of the relationship between the concentration of drugs and their corresponding responses in the assay.[3] (4) A graphical representation used to establish the linearity of response for the assay method of Gemfibrozil.[4] (5) A graphical representation describing the linearity of response for labetalol HCL assay method, established by preparing and injecting solutions of varying concentrations.[5]
