Экспериментальные данные получены для ультратонких пленок хрома на кремниевой подложке. Показано, что при сильном наклоне образца (80°) улучшается отношение сигнал/шум. Это позволило определить рекордно низкие для данного метода содержания хрома. Градуировочная характеристика для наклонного расположения образца получена расчетным путем с использованием метода Монте-Карло. Экспериментально определена поверхностная концентрация атомов хрома (2,2 ± 0,5) · 1014 см-2. Предел обнаружения хрома при предложенной конфигурации эксперимента составил около 5 · 1013 см-2. Для электронно-зондового микроанализа массивных образцов это значение является рекордным. Эквивалентная масса хрома при таком значении поверхностной концентрации составляет приблизительно 4 · 10-18 г. Реализация данного способа не требует внесения изменений в конструкцию прибора.</p></abstract><trans-abstract xml:lang="en"><p>The frontier of electron probe x-ray method in determination of the trace quantities of metal on a silicon substrate is studied. Experimental data are obtained for ultra-thin chromium films on a silicon substrate. It is shown that the signal - noise ratio significantly increases at a strong inclination of the sample (80°) which provides determination of extremely low (for this method) chromium content. Calibration curve for inclined sample position is obtained using Monte Carlo method. Surface concentration of chromium atoms (2.2 ± 0.5) × 1014 cm-2 and chromium detection limit (5 × 1013 cm-2) are determined experimentally for the given configuration of the experiment. For electron-probe microanalysis of bulk samples this is a record value. The equivalent mass of chromium at aforementioned value of the surface concentration is approximately 4 × 10-18 g. Implementation of the method does not require changes in the of the device design.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электронно-зондовый рентгеноспектральный анализ</kwd><kwd>нанопленки</kwd><kwd>предел обнаружения</kwd><kwd>хром</kwd><kwd>кремниевая подложка</kwd><kwd>electron probe x-ray analysis</kwd><kwd>nanofilms</kwd><kwd>detection limit</kwd><kwd>chromium</kwd><kwd>silicon substrate</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">Opila R.
