Vapor-phase infrared spectroscopy on solid organic compounds with a pulsed resonant photoacoustic detection scheme (original) (raw)

Novel Optical Instrumentation for Biomedical Applications II, 2005

Abstract

There is a great need for a low cost and sensitive method to measure infrared spectra of solid organic compounds in the gas phase. To record such spectra, we propose an optical parametric generator-based photoacoustic spectrometer, which emits in the mid-infrared fingerprint region between 3 and 4 microns. In this system, the sample is heated in a vessel before entering
