Unified principles of univariate analytical calibration

Pawel Koscielniak

Summary: An attempt has been made to build a revised and logical concept of univariate analytical calibration in qualitative and quantitative analysis. The study focuses on the similarity between the real and model calibration functions as a condition for correct calibration and reliable analytical results. It is found that the similarity of both functions depends on the elimination and/or compensation of uncontrollable analytical effects. The research demonstrates that every method of qualitative and quantitative analysis requires analytical calibration, including methods commonly considered as absolute or standardless ones.
