摘要： An apparatus for measuring the Sulfur component contained in oil includes an X-ray tube having a target made of Titanium or Scandium, a filter made of Titanium or Scandium for filtering said X-ray radiated from the X-ray tube, a measurement cell for introducing a sample to be measured therein, and a detector for detecting fluorescent X-rays radiated from the sample. According to the invention, the X-ray tube has a target made of Titanium or Scandium and the X-rays generated from the X-ray tube are filtered by the filter, which is made of Titanium or Scandium, so that the background of the X-rays for the measurement against the fluorescent X-rays of the Sulfur is reduced and therefore even a small amount of Sulfur contained in the sample can be correctly detected.

摘要： An X-ray analyzing apparatus according to the invention includes an excitation ray generator for applying an excitation ray onto a sample, and an X-ray detector which is sealed in a vacuum container along with a cooling device; a first X-ray passing layer, where a first gas exists, is provided in a path through which the characteristic X-ray generated from the sample travels to the X-ray detector; X-ray transmission windows are provided on the first X-ray passing layer and on the vacuum container so as that the characteristic X-ray can reach to the X-ray detector through the windows; the first and second X-ray transmission windows are separated from each other so as to provide a second X-ray passing layer therebetween; and the second X-ray passing layer is arranged to be a vacuum or a second gas is circulated through the second X-ray passing layer. According to this construction, it can be prevented that the first gas breaks into the vacuum container in which the X-ray detector is sealed; thus the deterioration of the cooling efficiency caused in that the vacuum condition in the vacuum container is decreasing prevented, so that the consuming amount of the cooling medium for use in cooling the X-ray detector can be reduced.

摘要翻译： 根据本发明的X射线分析装置包括用于将激发光线施加到样本上的激发光线发生器和与冷却装置一起密封在真空容器中的X射线检测器; 其中存在第一气体的第一X射线通过层设置在从样品产生的特征X射线行进到X射线检测器的路径中; 在第一X射线通过层和真空容器上设置X射线透射窗，使得特征X射线可以通过窗口到达X射线检测器; 第一和第二X射线透射窗口彼此分离，以便在它们之间提供第二X射线透过层; 并且第二X射线通过层被布置为真空，或者第二气体通过第二X射线通过层循环。 根据该结构，能够防止第一气体分解成密封有X射线检测器的真空容器内， 因此，由于真空容器内的真空状态的降低而导致的冷却效率的劣化，能够降低用于冷却X射线检测器的冷却介质的消耗量。
