The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
CBD-liquids investigated in this study, only 30% of the samples contained an amount of CBD that was within 10% deviation of the label claim. Moreover, the CBD e-liquids labelled “full/broad spectrum” consisted ...
Spectroscopic approaches for conformity analysis of e-liquids
taurine, vitamin E and CBD in e-liquids. Therefore a set of 236 e-liquids was selected. Since samples with caffeine, taurine, CBD and vitamin E as additives were hard to find, some of the samples were split ...
