    Evaluation of Cl in blood by NAA and XRF techniques
    2019 - MELO, JULIANA S.; ZAMBONI, CIBELE B.; AZEVEDO, MARIA R.; KONSTANTYNER, TULIO
    The objective of this work is to analyze Cl in whole blood of newborns, concomitant with the traditional collection of “the heel prick test” (fourth drop). The dosage of Cl in whole blood samples of twenty newborns were determined by Energy Disperse X-Ray Fluorescence (EDXRF) and the Instrumental Neutron Activation Analyses (INAA) analytical techniques. Particularly, the alternative methodology based on EDXRF technology, using a portable XRF spectrometer, showed to be a fast and efficient procedure for Cl dosage in whole blood. We intend to introduce benefits to clinical practice in children, especially newborns and premature infants using this alternative procedure.
