[Determination of copper, zinc, calcium, magnesium and iron microelements in whole blood samples from human's ear...

This paper established a new and convenient method for the determination of Cu, Zn, Ca, Mg and Fe microelements content in whole blood samples from human's ear by using flame AAS with microsample injection. The results show that recoveries of these microelements are above 96.0% and relative standard deviation of Zn, Ca, Mg and Fe are less than 2.0%, Cu is less than 3.9%. Satisfactory results are obtained with only 10 microL whole blood samples from human's ear.
