The analysis of emissions from tobacco heating products presents a number of challenges. These include: ensuring that testing conditions are relevant to the mechanism of operation and to known or expected consumer use; design of representative sampling conditions; and ensuring that the testing, measurement or analytical method is fit for purpose.

As well as constituents that are known to be present in the tobacco consumable, a number of additional constituents may be found in the aerosol that are associated with the heating device or due to thermal degradation. In order to inform product understanding and to assure due diligence, testing methods are required to screen the chemical constituents of tobacco heating product emissions.

Further to the presentation by Rawlinson et al at the 68th TSRC in 2014, this presentation will demonstrate the evolution of the method from separate particulate and vapour phase trapping using Cambridge Filter Pad collection and sorptive trapping (respectively) to sorptive trapping alone, and the benefits this provides. In addition, developments in the gas chromatographic analysis and data processing will be highlighted.
