Abstract
An x-ray analysis system with an x-ray source for producing an x-ray excitation beam directed toward an x-ray analysis focal area; and a sample chamber for presenting a fluid sample to the x-ray analysis focal area. The x-ray excitation beam is generated by an x-ray engine and passes through an x-ray transparent barrier on a wall of the chamber, to define an analysis focal area within space defined by the chamber. The fluid sample is presented as a stream suspended in the space and streaming through the focal area, using a laminar air flow and/or pressure to define the stream. The chamber's barrier is therefore separated from both the focal area and the sample, resulting in lower corruption of the barrier.
