We developed a hybrid X-ray focusing optics, which consisted of a polycapillary X-ray lens (PCXL) and a tungsten conical pinhole (WCP) for micro X-ray fluorescence (μ-XRF) analysis. A single PCXL produced an X-ray micro beam with a spot size of 12

Using atomic emission spectrometry, it is difficult to achieve high-sensitivity analysis of chlorine, due to its high excitation energy. Only 5% of the total sample volume contributes to the emission intensity, using a nebulizing system of inductivel
