Calibration methods in qualitative analysis

The aim of this study is to show that each analytical procedure in qualitative analysis is based, as in quantitative analysis, on the calibration process. The identification of an analyte requires the use of a standard which may be of a chemical, biological or mathematical nature. The method of treating the sample and standard with or without additional reagents determines the calibration method used. It was shown that calibration methods in qualitative analysis have a similar structure and role as in quantitative analysis. The problem of the influence of uncontrolled analytical effects on the accuracy of the results of identification analyses was also discussed. Considerations are supported by numerous experimental examples.(c) 2022 Elsevier B.V. All rights reserved.
