摘要:
本文将三乙醇胺针对硫化氢（H2S）的特异选择性吸附与声表面波传感技术的快速与高灵敏响应特点相结合，提出了一种基于声表面波的硫化氢快速检测技术。利用滴涂方法实验制备了在声表面波传播路径表面沉积三乙醇胺的延迟线型基传感器件，并结合差分鉴相电路，研制出SAW硫化氢气体传感系统样机。针对硫化氢气体传感实验结果显示，所研制的声表面波硫化氢传感器具有快速响应（≤30s）、高灵敏度（4.27mV/ppm）和较低的检测下限（0.14 ppm）的特点，在硫化物快速监测应用领域具有良好的应用前景
Abstract:
In this contribution, a surface acoustic wave (SAW) based H2S sensor was proposed for by combining the SAW technology with fast response and TEA with selective absorption towards H2S. By means of the drop-coating method, a 200MHz SAW H2S sensing device with delay line configuration was developed, and collected into the differential phase discrimination circuit, and the corresponding SAW H2S sensor system was constructed. The measured results in H2S gas experiments indicates that fast response (≤30s), high sensitivity (4.27 mV/ppm) and lower detection limit (0.14 ppm) were achieved. It means the proposed SAW sensor will be promising for sulfide sensing
