A preliminary laboratory evaluation of commercially available portable XRFs from three (3) manufacturers was performed. The purpose of the evaluation was to compare one instrument from each manufacturer on as equal a basis as possible, for their biases and precisions when measuring lead in paint films laid over various substrates. Lead concentrations in the films ranged from 0 to 7.16 mg/sq.cm. Eight different substrates of varying densities were used to represent the types of building materials most likely to be encounterd in the field. Conclusions from this limited comparison as well as recommendations for future comparisons are presented.
