Carbon Monoxide Content

AbstractCarbon monoxide is found in the gas phase of cigarette smoke in relatively high quantities. In the present study a quantitative method for the determination of carbon monoxide in tobacco smoke by gas chromatography was used. The construction of a calibration line by means of carbon monoxide produced in the laboratory is indicated and the experimental procedure is described. Furthermore the relation between the carbon monoxide content in smoke and different parameters of the test cigarettes is evaluated. The carbon monoxide content in the smoke of various tobacco blends is determined. An increase of the carbon monoxide content in the smoke is observed after the extraction of sugars from the tobacco. The carbon monoxide content increased from puff to puff when the cigarettes were smoked. Cigarette weight had no influence on carbon monoxide in the smoke. This applies also to the humidity of the tobacco, the acetate filters and the carbon filters. Puff volume and the perforation of cigarette paper, however, influenced the carbon monoxide yield considerably.

Abstract Gas-solid chromatographic methods are presented for the determination of carbon monoxide, carbon dioxide, or both simultaneously in the gas phase of cigarette smoke. The methods are optimized to allow quantitative determinations on the entire gas phase delivery of the cigarettes rather than single puffs and to allow the use of small numbers of cigarettes. Shortcomings of several sampling techniques are defined, and evidence is presented supporting the utility of Saran bag sampling and containment. Carbon monoxide and carbon dioxide analyses may be performed with relative standard errors of 2—3% and relative confidence intervals (95%) of 6—9% for determinations involving 4—6 cigarettes.

AbstractNitric oxide in cigarette smoke was conveniently determined by non-dispersive infrared analysis (NDIR). Recoveries of 95 % were obtained with standard gas-air mixtures but recoveries from smoke increased from 87% for high-yield to 91 % for low-yield cigarettes. Relative error was about 4 %. A reduction in the dead volume of Cambridge filter cassettes, to reduce the amount of NO reacted between puffs, increased NO deliveries of cigarettes by 4%. Deliveries of NO were estimated to average 4 % lower due to oxidation, but reaction with other smoke components reduced them further depending upon concentrations. The NO deliveries of cigarettes increased as blend nitrate increased and as the flow of air around cigarettes decreased. Nitric oxide in smoke and in standard gas-air mixtures, determined by non-dispersive infrared (NDIR) spectroscopy, was substantiated by an automated colorimetric analysis. Interfering smoke species were determined and circumvented in both methods.

Quick Determination

Abstract A flameless atomic absorption method has been developed which permits the quick determination of the levels of trace metals in cigarette smoke. The total particulate matter (TPM) was collected by electrostatic precipitation and dissolved in methanol before analysis. In order to trap the last remaining traces of metals, the gas phase was passed through microporous filters which were analysed direct. The sensitivity of this method for the metals studied (Zn, Pb, Cd, Ni) is good in both the particulate and gas phase samples, with the sole exception of Ni in the gas phase. Results obtained by the flame and flameless methods are compared.
