The presentation2 noted that LA-ICP-MS
offers a unique facet to process mineralogy and pointed out that many economic metals are present at ultra-low levels in mineral deposits and require complex recovery techniques to separate them from the bulk ore.
data was analyzed and converted into 2D elemental images using Applied Spectra, Inc.'s Data Analysis Software.
This time span is much longer than the signal spike (e.g., <3 seconds) obtained by LA-ICP-MS
analysis of C[O.sub.2]-rich fluid inclusions at room temperature, thus enabling recording of more sampling cycles.
Dos muestras fueron procesadas para ser analizadas por el metodo U-Pb (LA-ICP-MS
), de cada una fueron obtenidas imagenes de catodoluminiscencia (CL, FIGURA 7).
Trace elements were analyzed in six pyrite samples using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS
) at the U.S Geological Survey in Denver.
In this study, Tm-DOTMA is introduced as possible lymph marker, in addition to Gd-DO3A-butrol, and the kinetics of both contrast agents is quantitatively analyzed by LA-ICP-MS
in rat lymph nodes.

," Journal of Analytical Atomic Spectrometry, vol.
Because laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS
) can provide spatially resolved information at detection limits of ppm for many elements (Jimenez et al.
The same samples were also analyzed with mass spectroscopy (LA-ICP-MS
) by Shiva Technologies, Syracuse, NY, detecting 78 elements ranging from lithium to californium and 108 isotopes ranging from 7Li to 249Cf.
We report here on the chemical analysis by portable x-ray fluorescence (PXRF) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS
) of 438 obsidian flakes recovered from Sepik coastal sites spanning the last two millennia of prehistory.
