Application of LA–ICP–MS in polar ice core studies [PDF]
Analytical and Bioanalytical Chemistry, 2003 The direct determination of element signatures in polar ice core samples from Greenland by laser ablation with subsequent inductively coupled plasma mass spectrometry analysis has been investigated. A cryogenic sample chamber enables the element determination in ice directly from the solid (frozen) state.

U‐Pb dating of zircon by LA‐ICP‐MS [PDF]
Geochemistry, Geophysics, Geosystems, 2006 In this study we used LA‐ICP‐MS (laser ablation–inductively coupled plasma–mass spectrometry) to determine U‐Pb ages of 5 zircon samples of known age (∼1800 Ma to ∼50 Ma) in order to determine the reproducibility, precision, and accuracy of this geochronologic technique.

Whole-rock trace element analyses via LA-ICP-MS in glasses produced by sodium borate flux fusion
Brazilian Journal of Geology, 2021 Trace elements provide crucial information about the origin and evolution of the Earth. One common issue regarding their analyses is the reduced analyte recovery during hot plate acid digestion for some geological samples. To overcome this, alkali fluxes
