The LSCE X-ray Fluorescence (XRF) lab includes two equipements that provide the elemental composition of samples, most of the time marine and terrestrial sediments.
XRF core scanner
The 4th generation Avaatech XRF core scanner (bought in 2019) provides semi-quantitative, high-resolution (cm to submm, down to 100 µm) measurements of the chemical composition of marine and continental sediments.
This semi-quantitative analysis gives access to the contents of major and minor elements (Mg to Ba), in an ultra-rapid and non-destructive manner, and with a very limited preparation of sediment cores.
ED-XRF spectrometer
The benchtop PANalytical Epsilon 3XLE ED-XRF spectrometer (bought in 2018) provides quantitative measurements of the chemical composition of ground samples.
It gives access to the concentrations of 19 major and minor elements (Mg to Ba) of sediment samples, in a rapid, non-destructive manner, and with a limited preparation of sediment samples.
