A portable total reflection X-ray fluorescence spectrometer is presented. The present spectrometer mainly consists of a 1.5-W X-ray tube, a waveguide type slit, a detector, and a sample carrier (a quartz optical flat), and these components are contained in an attache case-type box. Continuum X-rays emitted from the low-power X-ray tube are used for the excitation of the X-ray fluorescence, and the minimum detection limit for Cr is a few nanograms or the level of 1013 atoms/cm2.
介绍了一种便携式全反射X射线荧光光谱仪。该光谱仪主要由一个1.5瓦的X射线管、一个波导型狭缝、一个探测器和一个样品载体（石英光学平板）组成，这些部件装在一个公文包式的盒子里。低功率X射线管发出的连续X射线用于激发X射线荧光，Cr的最低检测限为几纳克或1013原子/平方厘米的水平。
