Dual imaging of uranium ore by Laser Ablation Inductively Coupled Plasma Mass Spectrometry and Laser Induced Breakdown Spectroscopy

Atomic spectrometry update – a review of advances in environmental analysis

“…An exciting development in recent years has been the potential afforded by the integration of LIBS data with data obtained by complementary techniques such as LA-ICP-MS. This was demonstrated 241 in the elemental imaging of a uranium ore sample prepared as a thin section. A preliminary view of the elemental distribution on a large area was obtained by LIBS and then a detailed survey of selected areas was performed using LA-ICP-MS. Specially-developed software allowed the imaging data from the two techniques to be merged so that detailed structures (from ICP-MS) could be superimposed on the overall sample image obtained by LIBS.…”

“…In a multielement method, N 2 O was preferred 188 to O 2 in the ICP-MS/MS collision/reaction cell because it improved sensitivity and selectivity for the determination of "technologically critical elements" in sediments. A procedure for ultra-trace level quantication of 241 Am in soils involved 189 radiochemical separation followed by the introduction of 0.09 mL min −1 He containing 20% O 2 and 12 mL min −1 He reaction/collision gas mixture into the cell for determination of the isotope in mass-shi mode as AmO + . The LOD was 0.017 fg g −1 .…”

Laser-Induced Breakdown Spectroscopy Imaging for Material and Biomedical Applications: Recent Advances and Future Perspectives

“…In this regard, the combination of typical LIBS imaging for atomic and molecular emission, as well as luminescence, allowed easy imaging of elements such as Eu, Gd, or Sm, 104 with extremely competitive LoDs of 10, 40, and 40 ppm, respectively. Finally, we present the possibilities offered by combining two different but complementary techniques: LA-ICP−MS and LIBS imaging of uranium ore. 105 Briefly, LIBS was used to perform a rough and rapid scan to map the total area. Then, LA-ICP− MS was used in specific and restricted areas where U was detected.…”

Laser-induced voltage of table salt for deep ultraviolet pulsed laser detection

“… 1 , 2 , 3 , 4 , 5 Since optical, acoustical, and electromagnetic phenomena, reflecting the sample characteristics, are generated after laser-induced plasma (LIP), quantitative and qualitative analysis of the sample can be achieved by these phenomena. 6 , 7 , 8 , 9 , 10 It is crucial to measure the characteristics of the pulsed laser, especially for the real-time detection of single-pulse laser energy. With the development of laser measurement process, thermopile energy system, and wide-gap semiconductor detection materials are widely applied.…”
