Quantifying PG : VG ratio and nicotine content in commercially available e-liquids using handheld Raman spectroscopy

Electronic cigarettes have become a popular alternative to traditional smoking, with e-liquids being a key component. Accurate analysis of their ingredients, such as PG:VG ratios and nicotine levels, is essential for regulation and consumer safety.

This article discusses a method using handheld Raman spectroscopy, a portable and rapid technique, to quantify these components in commercially available e-liquids, offering a potential tool for public health monitoring and policy enforcement.

Understanding the composition of e-liquids is crucial for assessing their health risks and ensuring product safety. Rapid, portable analysis methods like handheld Raman spectroscopy can enhance regulatory capabilities and public health responses.

By enabling quick and accurate ingredient verification, this technology can help reduce the risks associated with unregulated or mislabeled e-liquids, ultimately protecting consumers and informing policy decisions.

Accurate analysis of e-liquid ingredients supports efforts to regulate nicotine products and prevent youth access. It also helps identify potentially harmful formulations, contributing to better health outcomes.

Implementing portable analytical tools can improve surveillance and enforcement, ensuring safer products in the market.

This technology can inform policymakers by providing reliable data on e-liquid compositions, aiding in the development of regulations and standards. It also facilitates enforcement of existing laws and supports public health initiatives.

Adopting such methods can lead to more effective regulation of nicotine-containing products, reducing their appeal and accessibility to vulnerable populations.
