Abstract
The article presents the analysis of the study results of samples for lead content by their determination on the atomic absorption spectrometer “Kvant-2AT”, taking into account the use of the microwave laboratory system PLP-01M and while the sample preparation in accordance with GOST 26929 “Raw materials and food product. Sample preparation. Mineralization to determine the content of toxic elements”. A fundamentally new method of the sample preparation is used in the microwave laboratory system PLP-01M. The decomposition was carried out in a closed system, i.e. sealed fluoroplastic vessels under the influence of high temperature, pressure and microwave field. The microwave field was created by a special generator-magnetron in the operating chamber of the furnace. According to the assessment results of the operational control of the measurement procedure applying samples for the lead control when the microwave laboratory system PLP-01M was introduced in the laboratory; the analysis procedure was found satisfactory.
