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 ...
Nine prohibited stimulants found in sports and weight loss supplements: deterenol, phenpromethamine, oxilofrine, octodrine, beta-methylphenylethylamine, 1,3-dimethylamylamine, 1,4-dimethylamylamine, 1,3-dimethylbutylamine (1,3-DMBA) and higenamine.

In utero exposure to parabens and early childhood BMI z-scores – Associations between placental ethyl paraben, longitudinal BMI trajectories and cord blood metabolic biomarkers
butyl (BuP)] were measured by ultra-performance liquid chromatography/tandem mass spectrometry in 229 placentas of the ENVIRONAGE birth cohort. The association with cord blood metabolic biomarkers ...
Concentrations and distribution of chlorinated paraffins in Belgian foods
chlorinated paraffins (SCCP s and MCCP s, respectively) in a wide range of food samples (n = 211) purchased in Belgium during 2020. Samples were analysed by gas chromatography-mass spectrometry (GC- MS) and ...
Production of Alternaria Toxins in Yellow Peach (Amygdalus persica) upon Artificial Inoculation with Alternaria alternate
chromatography-tandem mass spectrometry (UHPLC- MS / MS). The results showed that the growth of A. alternate and the AT s production were dramatically affected by the storage temperature. At 28 °C, the fungi grew rapidly ...
Development and application of a novel method to assess exposure levels of sensitizing and irritating substances leaching from menstrual hygiene products
extraction before ultra-high performance liquid chromatography coupled with a triple-quadrupole mass spectrometry analysis. Validation was performed according to the total error approach with acceptability ...
