Application of improved matrix dilution method in quantitative analysis of Ni-Co-Mn ternary precursor

Nukleonika
When using energy-dispersive X-ray fluorescence (EDXRF) to analyze Ni-Co-Mn (NCM) samples, if the standard sample's concentration greatly differs from the unknown sample's concentration, the traditional matrix dilution method requires repeated dilution ...
