Disponível em: http://repositorio.ipen.br/handle/123456789/32237.http://repositorio.ipen.br/handle/123456789/32237The performance of two compact X-Ray Fluorescence (FRX) spectrometers consisting of Ag and Au X-ray mini-tubes associated with a Si Drift detector was checked for clinical finality. Using the Energy Dispersive X-Ray Fluorescence technique (FRXDE) specific light elements of clinical relevance (Ca, Cl, K and Fe) were determined in human whole blood samples without chemical digestion using direct and non-destructive analysis, in air atmosphere. A comparative study between Ag and Au targets data was carried out and the results are in good agreement.178-186openAccessx-ray fluorescence analysisbloodquantitative chemical analysisclinical trialsdiagnostic usesCapítulo de livro10.22533/at.ed.1302113011616https://orcid.org/0000-0001-7766-2692
