Abstract :
A high temperature MEMS flow control device is developed to modulate the effluent of the gas chromatography (GC) column. The noise of electroantennogram (EAG) is reduced dramatically with the MEMS enabled chopper stabilization of the analytes and subsequent demodulation of the recorded EAG signal. With the MEMS-GC-EAG technology, the signal-to-noise ratio for detecting green leafy volatile is improved singificantly, while the detection limit of pheromone cis-11-hexadecenal with the antenna from male Helicoverpa Zea is pushed down to 10-pg level.
