A Trapping System for the Combined Determination of Total HCN and Total Gas Phase Aldehydes in Cigarette Smoke

Automated determination of hydrogen cyanide acrolein and total aldehydes in the gas phase of tobacco smoke

For some time there has been wordwide concern for the health risks of cigarette smoking. In several countries, including the United States, Canada and the United Kingdom, surveys of the tar and nicotine delivered by commercial brands of cigarettes are carried out and published. Recently carbon monoxide levels have also been measured. The combustion of tobacco products such as cigarettes also pr...

Spin Trapping of Radicals in Gas-Phase Cigarette Smoke

Since the spin trapping technique was developed and utilized to determine radicals in the gas phase (see reviews [1—3]), it has become attractive as a method of detecting radicals in gas-phase tobacco smoke. A first study of this sort was reported by Bluhm et al. in 1971 [4], while previous studies were forced to rely on the measurements of smoke condensate at liquid nitrogen temperature [5, 6]...
