Effect of technological characteristics of powder material on the fluorescence intensity of elemental analytical lines

摘要: The effect of technological and physical–mechanical characteristics powder irradiators on the fluorescence intensity elemental analytical lines was studied experimentally. Investigations were conducted with use ferroalloy powders different grain size, in bulk pelleted form, at various loads. A dependence line density powders, both constant pressure, that defined by variation particle size surface interaction forces found. Calculations revealed a correlation between dependences obtained effective absorption due to concentrations solid irradiation phase, caused variations autoadhesive properties particles. Variations pelleting pressure led similar other densities packing, roughness not exceeding several microns having considerable formation layer. parameters found have greatest materials.
