AN-NIR-070
Quantification of nicotine and glycerin in e-liquids using visible near-infrared spectroscopy
Summary
This Application Note describes a fast method for the simultaneous quantification of nicotine and glycerin in liquid mixtures used for electronic cigarettes. With visible near infrared spectroscopy (VIS-NIRS), results are available without sample preparation, thus making VIS-NIRS highly suited for fast quality control.
