Основу пробы удаляли путем парофазной отгонки германия в виде летучего тетрахлорида (GeCl4). Выбраны параметры работы микроволновой системы, галогенирующий реагент и условия отделения основы пробы более чем на 99 %. Разработана комбинированная методика количественного химического анализа (КХА) GeO2 методом атомно-эмиссионной спектрометрии с дугой постоянного тока (ДПТ-АЭС) с многоканальным анализатором спектров МАЭС производства «ВМК-Оптоэлектроника». Определено остаточное содержание германия в растворах, полученных после парофазной отгонки основы пробы. Показано, что пределы обнаружения (ПО) 46 элементов при ДПТ-АЭС анализе диоксида германия с предварительным концентрированием примесей находятся в диапазоне n · 10–8 – n · 10–4 % масс. Правильность комбинированной ДПТ-АЭС методики подтверждена экспериментом «введено – найдено».</p></abstract><trans-abstract xml:lang="en"><p>A method for trace element concentration in the microwave accelerated reaction system MARS 5 is developed. The vapor-phase distillation was used to remove high-purity germanium dioxide matrix as volatile germanium tetrachloride (GeCl4). We specified operating conditions of the microwave system and chose a halogenating agent and its volume. The method of quantitative chemical analysis of germanium dioxide by direct current arc atomic emission spectrometry (DCA AES) was developed. The unit for analysis is equipped with a multichannel spectrum analyzer MAÉS produced by «VMK-Optoélektronika». We also determined the residual content of germanium in the resulting solutions after vapor-phase distillation. The limits for detection of 46 trace elements in DCA AES analysis of germanium dioxide with preconcentration of trace elements ranged from 0.5 ng/g to 1 μg/g. We carried out validation of the combined procedure using «spike test».</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атомно-эмиссионная спектрометрия с дугой постоянного тока</kwd><kwd>предварительное концентрирование примесей</kwd><kwd>пределы обнаружения</kwd><kwd>высокочистый диоксид германия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>direct current arc atomic emission spectrometry</kwd><kwd>preconcentration of trace elements</kwd><kwd>high purity germanium dioxide</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">Патент РФ 2300784, G01T 3/06, G01T 1/202.
