Показано, что оптимизация таких параметров, как форма электрода, способ расчета интенсивности спектральной линии и время базовой экспозиции, приводит к расширению рабочего диапазона градуировочных графиков. Параметры дуговой плазмы (температура и концентрация электронов) аналогичны при возбуждении спектров сухих остатков водных растворов, слюны, сыворотки крови и сухого вина. Это делает возможным прямое (без минерализации) определение микроэлементов в данных пробах с пределами обнаружения на уровне мкг/л. При нанесении на электрод пробы растительного масла, оно, вероятно, впитывается вглубь и не поступает полностью в дуговую плазму, из-за чего прямой анализ невозможен. Тем не менее определение микроэлементов способом сухого остатка возможно в маслах после кислотного разложения пробы.</p></abstract><trans-abstract xml:lang="en"><p>Conditions for the analysis of liquid samples on a MFS-8 spectrometer upgraded with a MAES photodiode array by arc atomic emission spectrometry with dry residue technique are specified. It is shown that optimization of the electrode shape along with the method of calculating the intensity of the spectral line and time of the base exposure leads to the expansion of the operating range of calibration curves. The arc plasma parameters (temperature and electron density) are similar when the spectra of dry residues of aqueous solutions, saliva, blood serum, and dry wine are excited. This provides direct (without digestion) determination of trace elements in these samples with the detection limits at a level of μg/liter. When a sample of vegetable oil is deposited on the electrode, it is likely to be absorbed in depth and does not enter the arc plasma in full, which makes the direct analysis impossible. Nevertheless, the determination of trace elements in oils by the dry residue technique is possible after acid digestion of the sample.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атомно-эмиссионная спектрометрия</kwd><kwd>дуговой разряд</kwd><kwd>МАЭС</kwd><kwd>базовая экспозиция</kwd><kwd>твердотельный детектор</kwd><kwd>биологические жидкости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atomic emission spectrometry</kwd><kwd>arc discharge</kwd><kwd>MAES</kwd><kwd>base exposure time</kwd><kwd>solid-state detector</kwd><kwd>biofluids</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Taylor A., Catchpole A., Day M.
