Uncertainties related to linear calibration curves: a case study for flame atomic absorption spectrometry
Least squares linear regression is widely used in analytical chemistry. In practice a linear relationship between substance content and measured value still has been assumed based on the correlation coefficient criterion, although not recommended. Textbooks provide the necessary formulas for the fit...
