Quantification of Nicotine and Glycerin in E-Liquids Using VIS-NIRS

In this application note, Metrohm describes a fast method for the simultaneous quantification of nicotine and glycerin in the e-liquid mixtures used for electronic cigarettes. With visible near infrared spectroscopy (VIS-NIRS), results are available without sample preparation, making VIS-NIRS highly suited for fast quality control.
