In this study the sensorial performances of a four-channel quartz crystalmicrobalance implemented on a single quartz plate are reported and compared with those offour independent quartz crystal microbalances. Particular attention has been devoted to bothcross talk in responses and sensor sensitivity. A recently synthesized nanostructuredpolymer, poly[phenylacetylene-(co-2-hydroxyethyl methacrylate)], has been used aschemical interactive material. The interactions of our sensor system with relative humidityare also reported. The multichannel device shows a better homogeneity of the masssensitivity with a spread of the values less then 4% compared to a 50% spread observed inthe set of four microbalances.
本研究报告了在单个石英板上实现的四通道石英晶体微天平的传感性能,并将其与四个独立的石英晶体微天平的传感性能进行了比较。特别关注了响应中的串扰和传感器灵敏度。一种最近合成的纳米结构聚合物聚[苯乙炔-(共-甲基丙烯酸2-羟乙酯)]已被用作化学交互材料。还报告了我们的传感器系统与相对湿度的相互作用。与在四个微天平组中观察到的50%的分散度相比,该多通道装置显示出质量灵敏度更好的均匀性,其值的分散度小于4%。
