Electromembrane extraction of nicotine in inhaled aerosols from tobacco cigarettes, electronic cigarettes, and heated tobacco products.

Introduction:
This text is a scientific article that describes a new method for extracting and determining nicotine in the aerosols produced by tobacco cigarettes, electronic cigarettes, and heated tobacco products. The method combines electromembrane extraction (EME) with liquid chromatography and provides a faster, simpler, and more efficient way to measure nicotine concentration compared to existing methods. The article includes an experimental study that compares the nicotine concentration in the aerosols produced by different tobacco products.

Key points:

* The study proposes a new method for extracting and determining nicotine in aerosols using EME combined with liquid chromatography.
* The method is highly efficient, selective, and provides sample clean-up capability.
* The linear range for nicotine detection is 0.1-200 mg L-1 with a limit of detection of 0.02 mg L-1.
* The method has good precision, repeatability, and recovery rates.
* The method has been successfully applied to determine nicotine in aerosols produced by tobacco cigarettes, electronic cigarettes, and heated tobacco products.
* The nicotine concentration in aerosols produced by heated tobacco products and electronic cigarettes is lower than in tobacco cigarettes.
* The nicotine concentration in aerosols produced by heated tobacco products and electronic cigarettes varies depending on the brand and usage.

Main message:
The study presents a new and efficient method for extracting and determining nicotine in aerosols produced by tobacco products. The method is highly selective and provides sample clean-up capability, making it a valuable tool for researchers and regulators. The study also highlights the importance of monitoring nicotine concentration in aerosols produced by different tobacco products, including heated tobacco products and electronic cigarettes. The results show that the nicotine concentration in aerosols produced by heated tobacco products and electronic cigarettes varies depending on the brand and usage, emphasizing the need for further research and regulation in this area. Overall, the study highlights the importance of developing new and efficient methods for monitoring nicotine concentration in tobacco products, particularly as the use of heated tobacco products and electronic cigarettes continues to rise.
