Review and Classification of Univariate Interpolative Calibration Procedures in Flow Analysis

Abstract

A novel classification system introducing three main categories of the calibration methods—interpolative, extrapolative, and indicative—is suggested once more to be used in analytical chemistry. Then the univariate interpolative calibration procedures developed in the flow analysis are reviewed. In contrast to other similar reports, the present article does not present them with respect to instrumental aspects but as to how the measurement data recorded are interpreted and transformed into the analytical results. On such a basis, five groups of the calibration approaches have been specified. Finally, the particular groups of methods are compared with each other and discussed in terms of their analytical performance.
