The determination of macro- and trace elements in juices is an actual task for quality control of juice products. When analyzing juices, the sample acid mineralization step used in most modern techniques significantly increases the duration of the analysis, which may also affect the correctness of the obtained results. In this regard, it is expedient to apply multi-element methods with the possibility of analyzing a sample without a sample preparation step, for example, arc atomic emission spectroscopy with the excitation of the spectrum of the dry sample residue and flame atomic emission spectral analysis. In this paper, optimization of the analysis conditions is described, an increase of the linear range of the calibration dependence is revealed, the absence of a matrix influence is proved. The developed methods were used to analyze a series of juice samples, the results are in satisfactory agreement with the literature data.
