Abstract

The article states that in order to compare the results obtained while operating on the atomic absorption spectrometer “Kvant-2AT” applying the microwave laboratory system PLP-01M and during the sample preparation in accordance with GOST 26929 “Raw materials and food products. Sample preparation. Mineralization to determine the content of toxic elements”, on operating samples, the products were selected that most fully cover the range of results obtained during the research. Some research results and data analysis were carried out within 30 operating days. The data were obtained while working on the Kvant-2AT atomic absorption spectrometer, taking into account the application of the PLP-01M microwave laboratory system and while the sample preparation in accordance with GOST 26929. The average values obtained under repeatability conditions were put in the table. The analyte cadmium was supplemented to assess the accuracy of the obtained values. The implementation of sample preparation methods taking into account the microwave decomposition of the sample in the case of using the microwave laboratory system PLP-01M and while sample preparation in accordance with GOST 26929-94 achieves the precision of the analysis results both under conditions of repeatability and under conditions of intermediate precision.
