Изобретение может быть .использовано юри рентганоопектральном флуоресцентном дисперсионном и беэдиспероиоаном анализе иматериалов сложного химического состава.The invention can be used in the X-ray fluorescence dispersion dispersion analysis and in the bad analysis of complex chemical composition materials.

При осуществлений рентгеноопектрального флуоресцентного анализа по известным способам .дл  учета избирательных эффектов возбуждени  анализируемого элемента и поглощени  тервичиого излучени  атомами мешающего элемента ввод т поправки В интенсивности флуоресценции на тр.исутствие имешающего элемента, поэтому эти сп особы трудоемки и требуют знани  -концентрации мешающего элемента.When implementing X-ray fluorescent analysis by known methods, taking into account the selective effects of excitation of the element being analyzed and absorption of tervic radiation by the atoms of the interfering element, corrections B of the fluorescence intensity for the absence of the existing element are introduced, therefore these factors are laborious and require knowledge of the interfering element.

Цель изоб ретбни  - у|П ростить схему проведени  коли-чественного анализа сложны.х по хИ|Мичвако,му соста)ву .материалов.The purpose of the image book is to increase the scheme for carrying out quantitative analysis of complex materials for Michivaco, based on the composition of materials.

С этой целью наклон образца к направлению первичного излучени  и угол отбора флуоресцентного излучени  выбирают с учетом спектрального состава первичного излучени  таким образом, чтобы обеспеичть выполнение услови  полной взаимной компенсации эффектов избирательного возбуждени  атомов анализируемого элемента и избирательного поглощени  атомами мешающего элемента первичного излучени , причем вышеуказанные углы при небольших содержани х определ емого элемента устанавливают посто нными, не зависищими от химического состава проб.To this end, the sample slope to the direction of the primary radiation and the angle of selection of the fluorescent radiation is selected taking into account the spectral composition of the primary radiation in such a way as to ensure that the effects of the full excitation of the selective excitation of the atoms of the element being analyzed and the selective absorption of the elements of the primary radiation are met, the above angles small contents of the element being determined are established by constant, independent of the chemical composition of the pri about.

а при значительных содержани х этого элемента определ ют по ориентировочному значению его концентрации и предварительно найденным поглощающим характеристикам проб.and with significant contents of this element, it is determined by the approximate value of its concentration and the previously found absorption characteristics of the samples.
