Sample viscosity / flow rate control for heavy samples and its X-ray analysis application

摘要

An X-ray engine having an X-ray source for generating an X-ray excitation beam sent in the direction of the X-ray analysis focal region, and a sample chamber for providing a sample flow to the X-ray analysis focal region, the analysis focus A sample chamber disposed within a sample analysis region defined within the chamber, an X-ray detection path for collecting secondary X-rays and sending the X-rays toward the detector; X An x-ray permeable barrier on the wall of the chamber through which the line passes and a blocking structure that generates sample flow turbulence in and on the sample analysis region by partially blocking the sample analysis region An X-ray analysis system having a body. The blocking structure may be disposed asymmetrically about the central axis of the X-ray analysis focal region and / or the sample analysis region, and may be a round pin. A heating element may be used to heat the sample stream to improve the flow.
