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.

The effect of particle size of substrate and tritium gas pressure on the efficiency of Wilzbach tritiation of crystalline polycyclic hydrocarbons has been investigated. The hydrocarbons studied included naphthalene, biphenyl, phenanthrene, chrysene, pyrene, m- and p-terphenyls, and acridine. No simple relationship between ionization potential and tritium incorporation was observed. The effect of radical scavengers such as nitric oxide and moderators such as helium on the labelling process have been examined. Tritium incorporation in a polycyclic hydrocarbon is enhanced lf gas exposure occurs in the presence of benzoic acid. The results are discussed in terms of current theories proposed for tritium labelling based on gas-phase studies. In the condensed phase present data show that radical processes are important in Wilzbach labelling. This has been confirmed by a preliminary e.s.r. examination of naphthalene and anthracene in the presence of tritium gas.
