Resumo
This report describes a study about the feasibility of using a conventional digital camera, a cell-phone camera, an optical microscope,
and a scanner as digital image capture devices on printed microzones. An array containing nine circular zones was drawn using
graphics software and printed onto transparency film by a laser printer. Due to its superior analytical performance, the scanner was
chosen for the quantitative determination of Fe2+ in pharmaceutical samples. The data achieved using scanned images did not differ
statistically from those attained by the reference spectrophotometric method at the confidence level of 0.05.
