In this paper we evaluated a new micro-flow injector for the determination of the concentrations of Cu, Mg and Zn in mononuclear blood cells. This device analyzed sample volumes in the order of microliters by flame atomic absorption spectrometry; it is inexpensive, and easy to build and to adapt to the conventional injector of the atomic absorption spectrophotometer. Detection limits of 106, 65 and 37 microg L(-1) for Cu, Mg and Zn were obtained, respectively. The percentages of recovery tests were found between 98 and 110%.
