Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
However, one of the challenges encountered during the analysis of e-liquids is the presence of the highly abundant e-liquid matrix components propylene glycol and glycerol. In this study, headspace gas ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
glycol and glycerol matrix. The e-liquid matrix is viscous and greasy which may result in a faster deterioration of the GC-columns and deactivate the interaction with the active groups. To overcome this ...
Genotoxic evaluation of the liquids present in electronic cigarettes
the Ames test. However, they all induced a positive effect in the in vitro micronucleus test that was clearly more pronounced than the effect induced by the propylene glycol/glycerol matrix. Dark ...
Scientific opinion on the evaluation of the substances currently on the list in the annex to Commission Directive 96/3/EC as acceptable previous cargoes for edible fats and oils- Part III of III
isobutyl acetate, sec-butyl acetate, tert-butyl acetate, n-butyl acetate, propylene tetramer, paraffin wax, candelilla wax, white mineral oils and glycerol would not be of health concern as previous cargoes. ...
Nutrient sensing systems for rapid activation of the protein kinase A pathway in yeast.
growth on a respiratory carbon source, like glycerol or ethanol, is associated with low activity of the PKA pathway. We have studied how different nutrients trigger rapid activation of the pathway. Glucose ...
Impact of dilution on the pharmacokinetic behavior of acetaminophen in rabbits after oral administration
a concentrated small volume of an ethanol-glycerol-water mixture (preparation I). In another administration an identical dose was given in a 10-fold water-diluted volume of the same mixture (preparation II). Three ...
