Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry

liquid chromatography – tandem mass spectrometry (UHPLC- MS / MS) method for the simultaneous determination of four parabens (methyl-, ethyl-, propyl-, and butyl-paraben (MeP, EtP, PrP, BuP), four ...

A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies

ingredients, though also herbal adulteration occurs and is given less attention. In this paper a two-step approach is presented based on fingerprints recorded by both infrared spectroscopy as liquid ...

Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids

characterization of e-liquids of which gas-chromatography is the most often used technique as e-liquids mainly consist out of (semi)-volatile ingredients (i.e. nicotine and flavourings) dissolved in a propylene ...

Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population

profile, the two fractions were quantified separately using an online combination of liquid chromatography and gas chromatography with flame ionization detection (online LC- GC- FID). The detected MOSH and ...

DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS

A liquid-liquid extraction was used as a sample ‘clean-up’ for lubricants. The sample was then injected using gas chromatography-flame ionization-mass spectrometry (GC- FID- MS). The AHP s were analyzed using a HS- ...
