Química Nova, São Paulo, v. 37, n. 7, p. 1171-1176, jul. 2014.0100-4042e- 1678-7064http://repositorio.bc.ufg.br/handle/ri/16815This 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.porAcesso AbertoInstrumentationMicrofabricationTonerArtigo10.5935/0100-4042.20140189
