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

nicotine. Previous reports showed that nicotine concentrations are not compliant to the label claim, with mean deviations between 5% and 20%. Also zero liquids containing nicotine were encountered. Another ...

The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV

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 of several minor alkaloids ...

Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.

screening of e-liquid samples to check their compliance to the TPD i.e. non-nicotine labeled e-liquids should not contain nicotine and the maximum nicotine concentration of nicotine-labeled e-liquids should ...

CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up

CBD content not always corresponds to the label claim. There is a pressing need to develop new analytical methods specifically developed to the assay of such oily samples. Analytical issues are, ...

An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.

prothrombotic FXI a was assessed with confident identification of a 1ng/mg spike. Moreover, different residuals compositions were profiled for various commercial Ig products. Using a quantitative label free ...

Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.

the products is not always labelled, especially when they are bought through internet. Therefore there is a need for easy-to-use equipment and methods to perform a first on site screening of intercepted ...

Analysis of illegal peptide biopharmaceuticals frequently encountered by controlling agencies.

Additionally, we also show that when applying the same LC gradient, it is also possible to quantify these peptides without the need for derivatization or the use of expensive labelled peptides. This ...

HS-GC-MS method for the analysis of fragrance allergens in complex cosmetic matrices.

Cosmetic Regulation with labelling and concentration restrictions. This means that they have to be declared on the ingredients list, when their concentration exceeds the labelling limit of 10 ppm or 100 ppm ...
