Analysis of nitrogen oxides in THS aerosol
PMI
The objective of this method is to quantify the nitrogen monoxide (NO) and the sum of nitrogen dioxides (NO2) and nitrogen monoxide (NOx) in the Tobacco Heating System (THS) aerosol, referred to as Platform 1 (P1) in the method.
The method described is used to determine nitrogen oxides in mainstream aerosol from Platform 1 (P1) under Health Canada (HC) smoking regimen.

PMIScience.com is operated by Philip Morris International for the purpose of publishing and disseminating scientific information about Philip Morris International’s efforts in support of its smoke-free product portfolio. This site is a global site 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 advertising or marketing, nor is it directed at any specific market. It is not intended for use by consumers. New tobacco products sold in the United States are subject to FDA regulation; therefore the content of this site is not intended to make, and nor should it be construed as making, any product related claims in the United States without proper FDA authorization.
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. All of our RRPs are smoke-free products that deliver nicotine with far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
