Cigarette smoke is a highly complex matrix and presents analytical difficulties for the analyst performing compound identification by gas chromatography analysis coupled with mass spectrometric detection (GC–MS). The development of a novel trapping system and a modified GC–MS layout (using dual chromatographic columns and cryogenic focusing devices) has improved the chromatographic separation of volatile and semivolatile compounds found in cigarette smoke. This improvement has led to the potential to identify compounds usually masked by the solvent peak. This approach has also reduced the amount of peak overlapping by increasing the chromatographic peak capacity with the use of two capillary columns chosen for their analytical specificity.
PMIScience.com is operated by Philip Morris International for the purpose of publishing and disseminating scientific information about Philip Morris International’s efforts to develop and assess products that have the potential to reduce individual risk and population harm associated with tobacco use. This site is for use by scientists, the public health and regulatory communities, and other stakeholders with an interest in tobacco policy. The purpose of this site is not for advertising or marketing. It is not intended for use by consumers.
Reduced Risk Products ("RRPs”) is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking. PMI has a range of RRPs in various stages of development, scientific assessment and commercialization. Our RRPs are smoke-free products that produce an aerosol that contains far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
