Abstract

One of the highest interfering for the determination of VOC's in the sensoristic' s field, is the humidity. in this thesis my aim is to develop a physic system able of to reduce the humidity factor. For this reason has been tested the influence of humidity against some nano-gravimetric sensors based on of quartz oscillating with fundamental frequency of 20 MHz, with surface modified with Me-porphyrines and Me-corroles with Langmuir-Schaefer technique (LS) before and after the deposition of six layers of Poly-methyl methacrylate porous (PMMA). The decrease of sensibility' s against the humidity in sensor modified in surface with PMMA porous, compared to the same unmodified, observed in the tests, carried out us to assert, that this method could be useful for the future development of sensors that isn' t influenced of humidity.
