Background

Electronic cigarettes are handheld devices that simulate the feeling of smoking. The so-called E-liquid is vaporized by an electronically heated coil and the vapors are inhaled by the user. The liquid usually consists of propylene glycol, glycerol, flavors and nicotine.

Nicotine is a basic alkaloid that is naturally present in the tobacco plant. It is a psychoactive substance with both stimulant and relaxant effects and therefore an important component of the E-liquids.

Commercially available E-liquids have nicotine concentrations from 3 to 19 mg/mL. It is important to control and maintain the nicotine level in E-liquids to avoid any side effects of usage.
