Abstract: | The applicability of spectrochemical analysis of minute amounts of powder samples was investigated using an ultraviolet Nd-YAG
laser (355 nm) and low-pressure ambient air. A large variety of chemical powder samples of different composition were employed
in the experiment. These included a mixture of copper(II) sulfate pentahydrate, zinc sulfide, and chromium(III) sulfate n-hydrate powders, baby powder, cosmetic powders, gold films, zinc supplement tablet, and muds and soils from different areas.
The powder samples were prepared by pulverizing the original samples to an average size of around 30 μm in order to trap them
in the tiny micro holes created on the surface of the quartz subtarget. It was demonstrated that in all cases studied, good
quality spectra were obtained with low background, free from undesirable contamination by the subtarget elements and featuring
ppm sensitivity. A further measurement revealed a linear calibration curve with zero intercept. These results clearly show
the potential application of this technique for practical qualitative and quantitative spectrochemical analysis of powder
samples in various fields of study and investigation. |
