Determination of cobalt-rich crust fragments by portable X-ray fluorescence spectrometer Compass300

Portable X-ray fluorescence spectrometer is fast, nondestructive analysis of the characteristics of our research and development of portable X-ray fluorescence spectrometer Compass300 in rich cobalt crust fragment and shallow drill core field application of the in situ analysis using tablet sample of legal system, with rich cobalt crust national standard substance and polymetallic nodules national standards as the calibration samples, portable is established Type X-ray fluorescence spectrometer calibration curve method for determination of cobalt rich crust samples by national GBW standard substance 07339 validation, element Mn, Fe, Co, Ni and Cu precision (RSD) is between 0.3% ~ 3.0%, meet the requirements of rich cobalt crust sample analysis at the scene of the maritime resources exploration and application of portable X-ray fluorescence spectrometer Compass300 of rich cobalt crust fragment and shallow drill core is in situ analysis was carried out. Rich cobalt crust fragment the same data and laboratory test analysis directly after drying tablet sample preparation, compared to the XRF analysis data, Mn, Fe, Co, Ni and Cu element determination value of good consistency, shallow drill core analysis data in situ and laboratory artificial stratification analysis data comparison shows that the layers of Mn, Fe, Co, Ni and Cu elements directly test data and fact Test chamber
