Analytical smoke chemistry

10021_linear_30

Smoke chemistry analysis is a fundamental part of our research and development programme. It has ties into almost every area of our science from routine support to analysis of chemicals obtained from reduced toxicant prototypes to smokeless tobacco products.

Understanding smoke chemistry and characterising the chemistries from various product designs allows us to target constituents of interest and reduce them form the cigarette smoke using a variety of tools and techniques.

There are many challenges in this research field, as cigarette smoke is a highly complex dynamic aerosol suspended in an equally complex organic vapour mixture. More than 5000 smoke constituents have been identified in cigarette smoke and around 150 have been identified as toxicants. However, it is still unclear which toxicants are the most important in the various smoking related diseases.

The following pages describe the challenges associated with analysis of cigarette smoke constituents; the methodologies used; and the sophisticated equipment employed to generate cigarette smoke in a consistent and standardised manner.
