Abstract

Рентгеновский флуоресцентный анализатор содержит рентгеновскую трубку (402) для испускания падающего рентгеновского излучения (206) в направлении первой оптической оси (204). Блок (201) обработки пульпы выполнен с возможностью поддержания постоянного расстояния между пробой (202) пульпы и указанной рентгеновской трубкой. Первый кристаллический дифрактор (601) расположен в первом направлении от указанного блока (201) обработки пульпы и выполнен с возможностью выделения заданного первого диапазона длин волн от флуоресцентного рентгеновского излучения (207), которое распространяется в указанном первом направлении. Он выполнен с возможностью направления флуоресцентного рентгеновского излучения в выделенном заданном первом диапазоне длин волн на первый детектор (602, 505) излучения. Номинальная входная мощность указанной рентгеновской трубки (402) составляет по меньшей мере 400 Вт. Первый кристаллический дифрактор (601) содержит кристалл (603) пиролитического графита. Оптический путь между рентгеновской трубкой (402) и блоком (201) обработки пульпы является прямым без расположенного между ними дифрактора.
