Please Avoid Plotting Analytical Response against Logarithm of Concentration
Pawel L. Urban
Abstract
This perspective highlights a malpractice in handling calibration data sets. It refers to relating analytical response with logarithm of concentration, fitting such a data set with linear function, and deriving method characteristics from the slope of that function. A distinction is made between this malpractice and the proper use of logarithmic plots in representation of calibration data sets.
