| contents | Prototipo para la medición de H2S, basado en sensores piezoeléctricos para la evaluación de la halitosis Marielis Escalona Elinor Mejías Cristóbal Vega Lisbeth Manganiello Ingeniería H2S halitosis inverted microscopy Piezoelectric sensor quartz crystal microbalance This study presents the proposal of a prototype for the measurement of H2S, based on piezoelectric sensors for evaluation of halitosis. The design and construction of the cell where the piezoelectric sensor is located was raised for the development of research. The piezoelectric sensor is the device responsible for measuring levels H2S. The chemical system used was based on the reaction of H2S acidified aqueous medium and in the presence of inorganic mercury resulting in a stable precipitate HgS. This system provides the selectivity of the device as the other species that may be present remain in solution. Therefore the piezoelectric quartz microbalance sensor or records only the microprecipitate of HgS formed, which represents H2S indirect measure. The formation of microprecipitates was verified using inverted microscopy technique. To density calculate of each one the microprecipitates were used photometric techniques and numerical integration. The proposed prototype is presented as a simple, selective and sensitive evaluation device halitosis both healthy individuals and patients. 2016 artículo científico 1316-6832 https://www.redalyc.org/articulo.oa?id=70748810013 es http://www.redalyc.org/revista.oa?id=707 Revista INGENIERÍA UC application/pdf Universidad de Carabobo Revista INGENIERÍA UC (República Bolivariana de Venezuela) Num.3 Vol.23 |
