A novel “green” sample preparation method for portable X-ray fluorescence (pXRF) geochemistry of unconsolidated sediments as compared to traditional laboratory protocols
Abstract
Successful geochemical analyses utilizing in-field portable X-ray fluorescence spectrometry (pXRF) of unconsolidated glacial derived sediments is dependent on sample preparation to provide a consistent representation of the material being analysed. This study evaluates a novel, eco-friendly, “green” sample preparation technique – granular convection - for in-field pXRF spectrometry to acquire on-site real time geochemistry. This method eliminates the use of sieves and minimizes valuable in camp resources (time, solvents, brushes, air compressors etc.) by separating grain sizes through simple agitation of dried samples prior to analyses. Results from granular convection sample preparation followed by pXRF spectrometry are compared with laboratory sample preparation to
