Total-reflection X-Ray Fluorescence (TXRF) intensity profiles of Au L and M lines for two different chemical surrounding, i.e. metallic gold from sputtering as Au(0) and gold chloride as a deposition of Au(3+) standard solution in hydrochloride medium, show strong intensity differences out of the statistical fluctuations. These experimental observations could be explained considering the effect of

A micro X-ray fluorescence (μ-XRF) spectrometry instrument based on an assembled X-ray optics was constructed in the laboratory. The assembled X-ray optics consisted of a polycapillary slightly focusing X-ray lens and a tapered monocapillary X-ray lens (TMXRL). The output X-ray beam of the polycapillary slightly focusing X-ray lens was focused again by the TMXRL. A TMXRL with output aperture of 12

Laser induced breakdown spectroscopy (LIBS) based on femtosecond laser pulses has widely been used for analyzing chemical elements in samples. In this research, we achieved the double-pulse operation with a two-polarizer configuration, and the signal enhancement factor of 4–15 was observed as compared with the single pulse LIBS scheme. It is found that with the change in interpulse delay time between
