Internal quality control (IQC) is essential to ensure the reliability of the results of chemical analysis. In this study, we propose a novel method of IQC for multiresidue analysis of pesticides. A total of seven stable isotope labeled compounds (SILC) were added to analytical samples and were used to monitor and evaluate the quality of analytical results. In contrast to conventional IQC method in which only a limited number of control materials were analyzed to ensure the reliability of the results for an entire batch, the developed method can monitor the analytical quality of all the samples in the batch. It was shown that the developed method could achieve better performance than that of conventional method. Therefore, the developed method is considered to be promising for practical applications.(Received January 27, 2022; Accepted July 4, 2022).
