The purpose of this paper is to report our results on the detection and spectroscopic parameters of carbon monoxide, carbon dioxide and sulfur dioxide using high resolution linear diode laser spectroscopy with pulsed tunable PbS1-xSex homolasers. The parameters of pulsed diode lasers used in spectroscopy for various gases are discussed. The application of the diode laser spectrometer for CO gas detection at ppm level illustrates the sensitivity of the equipment.

Co Concentration

The e-fluid heated in electronic cigarettes (e-cigarettes) is largely composed of organic compounds, specifically propylene glycol, vegetable glycerin and flavouring compounds. When heated, as it is in an e-cigarette, the chemical species in this fluid have the potential to oxidise into carbon monoxide (CO) and other species. Using diode laser spectroscopy, the concentration of CO in e-cigarette mainstream effluent as a function of e-cigarette power and flavour was measured. Carbon monoxide concentration was found to be a direct function of the power of the resistive heating. At the highest powers testable using commercial e-cigarette components, the maximum CO concentration measured was over 180 ppm. The flavouring compounds in the e-fluid also had an effect on the concentration of carbon monoxide present in the effluent.
