Application of Corrected Methods for High-Resolution XRF Core Scanning Elements in Lake Sediments [PDF]
Applied Sciences, 2020 Contemporary studies emphasize theoretical and analytical aspects of monitoring water quality within lacustrine settings. The X-ray fluorescence (XRF) core scanner provides the most rapid, non-destructive high-resolution elemental measurements for ...

Rapid assessment of heavy metal pollution using ion-exchange resin sachets and micro-XRF core-scanning [PDF]
Scientific Reports, 2019 Conventional pollution monitoring strategies for heavy metals are often costly and unpractical. Innovative sampling and analytical approaches are therefore needed to efficiently monitor large areas.

Intercomparison of XRF Core Scanning Results From Seven Labs and Approaches to Practical Calibration [PDF]
Geochemistry, Geophysics, Geosystems, 2020 X‐ray fluorescence (XRF) scanning of marine sediment has the potential to yield near‐continuous and high‐resolution records of elemental abundances, which are often interpreted as proxies for paleoceanographic processes over different time scales ...

Practical guidelines and recent advances in the Itrax XRF core-scanning procedure [PDF]
Quaternary International, 2018 XRF core scanning has evolved to become a standard analytical technique for the rapid assessment of elemental, density and textural variations in a wide range of sediments and other materials, with applications ranging from palaeoceanography ...

Towards characterising rhyolitic tephra layers from New Zealand with rapid, non-destructive μ-XRF core scanning [PDF]
Quaternary International, 2019 Abstract Tephra layers are of importance for the construction of reliable age control in late Quaternary paleoenvironmental and volcanic hazard studies, especially in volcanically-active settings such as the North Island of New Zealand. However, their identification involves time-consuming and destructive processing steps, making the application of ...

Signal-to-noise ratios, instrument parameters and repeatability of Itrax XRF core scan measurements of floodplain sediments [PDF]
Quaternary International, 2018 This study used signal-to-noise ratios to assess the effects of increasing Itrax XRF instrument parameters, namely tube voltage, tube current and exposure time, on XRF spectra and measurement repeatability.

Identifying major paleoenvironmental changes in the southern Red Sea continental shelf with the use of high-resolution XRF-core scanning data [PDF]
Goldschmidt2021 abstracts, 2021 X-ray fluorescence core scanning (XRF-CS) has been proved to be an invaluable tool in paleoenvironmental and paleoclimatic research as it can provide continuous and high-resolution chemical records of marine sediment cores. The value of the produced data
