Analysis of substrates exposed to tobacco and components derived from tobacco

摘要

An innovative analytical method comprising the step of exposing a first substrate to at least one tobacco component, a tobacco composition, or at least one component derived from tobacco, such as, but not limited to, at least one tobacco smoke component. An additional step may comprise the step of preparing a second substrate not exposed to the tobacco component in an identical manner, wherein the second substrate may receive a different exposure, no exposure, or exposure in combination with another factor or condition, or any combination thereof. Additional steps may comprise collecting at least one first sample from the first substrate and at least one second sample from the second substrate, and analyzing the first and second sample by using at least one analytical characterization technique, wherein the analytical characterization technique comprises NMR spectroscopy. An additional step may comprise comparing the results of the analysis of the first and second samples using data pattern recognition techniques or metabonomic technology.
