ISO standards for analysis of mainstream smoke for ‘tar’, nicotine, and carbon monoxide (TNCO) have been in routine use for characterization of cigarettes in analytical testing laboratories for many years. While these methods are consistent and reliable, strict adherance to these methodologies requires defined time constraints. This presentation focuses on a proposed approach to generate and report TNCO results with a more rapid process with minimal impact on variability of reported values. Approaches to streamline sample collection, logging, and reporting data will be presented. Technical aspects of the ISO methodology for which modifications would yield efficiency improvements were explored. Results from evaluation of these variables will be presented. Results from the new method will be presented along with potential advantages and disadvantages to streamlining the TNCO method.
