Popis: The article considers specific features of schemes of X-ray fluorescence analysis of liquid samples in the geometry of thick layers and in thin layers using the X-ray optics scheme with total internal reflection. A scenario is proposed for the analysis of liquid samples in thin layers using a simple X-ray optics scheme lowering the detection limits 1000-fold in comparison with the traditional scheme in thick layers. The internal standard method is implemented to improve the reproducibility of the results. The proposed scenario was tested in the analysis of potable water.
