It outlines methodologies for single-point and multiple-point external standardization, emphasizing the limitations and considerations for each, such as determinate errors. It further delves into unweighted and weighted linear regression techniques, detailing equations for calculating slope and y-intercept while addressing error management.

In principle, it should be possible to derive the value of kA for any analytical method by considering the chemical and physical processes generating the signal. Unfortunately, such calculations are not feasible when we lack a sufficiently developed theoretical model of the physical processes, or are not useful because of nonideal chemical behavior.

It covers single-point and multiple-point standardizations, explaining that while single-point standardization is simpler, it has drawbacks due to potential errors and non-linearity in signal response. Multiple-point standardization, through calibration curves and methods like linear regression, offers a more accurate approach.
