Calibration curve linear range

WebMar 29, 2024 · E.A. Sanker. A calibration curve is a method used in analytical chemistry to determine the concentration of an unknown sample solution. It is a graph generated by experimental means, with the concentration of solution plotted on the x-axis and the observable variable — for example, the solution’s absorbance — plotted on the y-axis. WebBased on the Standard Deviation of the Response and the Slope. The detection limit (DL) may be expressed as: DL = 3.3 σ/ S. Where σ = the standard deviation of the response. S = the slope of the ...
