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.
