Quantitative analysis of trace elements in human blood and plasma by energy dispersive X-ray fluorescence.
A photon excitation, secondary target x-ray fluorescence system was used to measure concentrations of Cu, Zn, Br and Rb in whole blood and plasma of healthy adults. The samples preparation method and calculated limits of detection of the technique are reported. Correlation statistics for elemental concentrations have been determined. Verification of the results for copper was performed using atomic absorption spectrophotometry.
