Foliar Elemental Analysis of Brazilian Crops via Portable X-ray Fluorescence Spectrometry [PDF]
Sensors, 2020 Foliar analysis is very important for the nutritional management of crops and as a supplemental parameter for soil fertilizer recommendation. The elemental composition of plants is traditionally obtained by laboratory-based methods after acid digestion ...

X-ray fluorescence spectrometry at GGU
Rapport Grønlands Geologiske Undersøgelse, 1975 In 1971 GGU started to establish a modern laboratory for rock analysis based on X-ray fiuorescence spectrometry and a manual Siemens SRS sequence spectrometer, prepared for automation, was bought. It is difficult to imagine a modern X-ray spectrometer without automatic preselection of measuring parameters but the automation can be present in varying ...

Fluorescence correction for activity measurement of 93mNb in niobium dosimeters: Calculation and experimental validation [PDF]
EPJ Web of Conferences, 2023 Niobium is a dosimeter used to characterize fast-neutron reaction rates to monitor nuclear reactor vessels. Its characterization is based on the activity of 93mNb resulting from the 93Nb(n,n’) activation reaction. The decay of 93mNb results mainly in the
