Advances in Tropical Soil Characterization via Portable X-Ray Fluorescence Spectrometry

Pedosphere, 2019
Portable X-ray fluorescence (pXRF) spectrometers can be used to determine the elemental composition easily, rapidly, and without using chemical reagents, which is very important for tropical regions due to the lack of detailed soil characterization data.

Atomic Spectrometry Update—Inorganic Mass Spectrometry and X-ray Fluorescence Spectrometry

J. Anal. At. Spectrom., 1988
This year's Update includes an extended mass spectrometry section based on full abstracts and covering fully this extensive area of analysis. The newly introduced instrumentation for Glow discharge MS and the combined MS techniques are particularly notable this year. The ICP-MS section continues to grow in line with the increasing number of instruments
