摘要： An x-ray analysis system having an x-ray engine with an x-ray source for producing an x-ray excitation beam directed toward an x-ray analysis focal area; a sample chamber for presenting a sample stream to the x-ray analysis focal area, the analysis focal area disposed within a sample analysis area defined within the chamber; an x-ray detection path for collecting secondary x-rays and directing the x-rays toward a detector; an x-ray transparent barrier on a wall of the chamber through which the x-rays pass; and a blocking structure partially blocking the sample analysis area, for creating sample stream turbulence in the sample analysis area and over the barrier. The blocking structure may be disposed asymmetrically about a central axis of the x-ray analysis focal area and/or the sample analysis area; and may be a rounded pin. A heating element may be used to heat the sample stream for improving flow.
