Carbon Black Absorption Enhanced Fiber-Optic Photoacoustic Gas Sensing System with Ultrahigh Sensitivity.

Analytical Chemistry
A highly sensitive trace gas sensing system based on carbon black absorption enhanced photoacoustic (PA) spectroscopy (PAS) is reported. A carbon black sheet and a fiber-optic cantilever microphone (FOCM) are integrated to form a fiber-optic cantilever ...
