摘要

快速检测挥发性有机化合物(VOCs)的气相色谱-声呐(GC-SAW)系统得到了发展。检测限取决于系统的响应和频率的基线噪声。频率基线噪声包括振荡器噪声和频率温度系数噪声。SAW传感器的TCF很难去除，因此本文的优化是基于SAW振荡器和恒温器。

Optimization frequency baseline noise of saw sensor in SAW/GC system

The GC-SAW system which can rapidly detect volatile organic compounds (VOCs) has been development. The detection limit depends on both response and the baseline noise of frequency in this system. The frequency baseline noise includes the Oscillator noise and temperature coefficient of frequency (TCF) noise. The TCF of the SAW sensor is hard to remove, so the optimization is base on both SAW oscillator and the thermostat in this paper.
