摘要：
In the space restricted airtight environment that people lives in, detecting harmful gas by miniature gas chromatography is the practical requirement at present, however, PID's performance is key factor that restrict the application of miniature gas chromatography, the redesign of the detector's gas route in this paper aiming at improve detector's stability observably, and schemed out miniature PID with high sensitivity, low detection limit and fast response. The result of the experiment shows that the detection limit is 0.04ppm, the sensitivity is 101mv/ppm,the stability is 0.04x10-6/24h,meeting the project requirement.
