摘要: A method of using photoacoustic spectroscopy to determine chemical information about an analyte includes the steps emitting a light ray for interaction with sample analyte; transmitting through fill fluid disposed in detection cell, having molecules substantially similar absorb ray; producing thermal wave and oscillation proportional intensity including pressure by wave; detecting microphone
