Application of the PLP-01M microwave laboratory system using control samples to assess the accuracy of the results of studies of cadmium content

Abstract

Abstract This paper considers and analyzes the results of examining samples for cadmium content by determining them on a Kvant-2AT atomic absorption spectrometer, taking into account the use of the PLP-01M microwave laboratory system and during sample preparation in accordance with GOST 26929 “Raw materials and food products. Sample preparation. Mineralization to determine the content of toxic elements”. The PLP-01M microwave laboratory system uses a fundamentally new method of sample preparation. The decomposition was carried out in a closed system - sealed fluoroplastic vessels under the influence of high temperature, pressure and microwave field. The microwave field in the working chamber of the furnace was created by a special generator-magnetron. Based on the results of the assessment of the operational control of the measurement procedure using samples for cadmium control during the implementation of the PLP-01M microwave laboratory system in the laboratory, the analysis procedure was recognized as satisfactory.
