Abstract

Continuous wave -terahertz spectroscopy by photomixing is applied to the analysis of mainstream cigarette smoke. The spectral signatures of hydrogen cyanide (HCN), carbon monoxide (CO), formaldehyde (H₂CO) and water (H₂O) have been observed and examined from 500 GHz to 2400 GHz, allowing direct concentration measurement from the rotational transitions. The quantification of the analysis was validated by the measurement of a calibration gas containing CO. The potential of this technique trace gas detection has also been demonstrated with an estimated detection limit in the ppm.m range.
