Аннотация
Determination of the total concentration (сΣ) of similar organic compounds as an total index (TI), expressed in terms of a standard substance of Xst, is a widely used but poorly studied type of chemical analysis. The main problem is the inaccuracy of estimate сΣ. The article considers reasons for the appearance of systematic errors, rules of formation of groups of simultaneously determined compounds, and the choice of Xst. A classification of TI taking into account the nature of Xst is proposed. To improve the accuracy of analysis, it is expedient to simultaneously use of several standards and construct multivariate calibration dependences.
