AbstractA gas chromatographic method for the determination of carbon monoxide and carbon dioxide in cigarette smoke was developed. A column containing Porapak Q packing and a cryogenic temperature programmer which employed liquid nitrogen to cool the column to subambient temperatures was used. The separation of N

1. A rapid method for the analysis of CO in expired air has been developed, which is suitable for use in studies of smoking. 2. The Bohr equation has been used to calculate the mean alveolar CO partial pressure (Pa,co). 3. The values of Pa,co obtained are highly correlated with direct measurements of venous carboxyhaemoglobin (r = 0·96). 4. The method will distinguish between populations of smokers and non-smokers, and can allow the changes of CO in a smoker throughout a 12 h period to be followed. It provides a measure of the dose of cigarette smoke (vapour phase) that results from smoking a single cigarette.

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.

AbstractA system for the in-line measurement of puff-by-puff levels of carbon monoxide on a Filtrona 300 smoking machine during routine smoking of cigarette for tar and nicotine yields has been developed. The technique involves the introduction of a transducer into the suction line behind the Cambridge filter. This transducer comprises an electrochemical cell bridged by a pair of solenoid valves which are under the control of the cotton gate smoking terminator. These valves are actuated, other than at the butt mark, by an additional inductive timing switch on the crankshaft. Results using this technique compare well with results from existing off-Iine techniques such as gas-solid chromatography
