DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS

step and a salting-out assisted liquid-liquid extraction procedure were developed and op-timized. An ultra performance liquid chromatography – triple quad mass spectrometry (UPLC- TQMS) method with a run ...

Weight and head circumference at birth in function of placental paraben load in Belgium: an ENVIRONAGE birth cohort study

propyl (PrP), and butyl (BuP)) were determined by ultra-performance liquid chromatography coupled with tandem mass-spectrometry. Generalized linear regression models were used to determine the association ...

Publication Type: Scientific poster, presentation or proceeding Authors: Svetlana V. Malysheva; Mulder PPJ; Julien Masquelier Source: RAFA 2019 (2019) Service:  Contaminants organiques et additifs Organische contaminanten en additieven Organic contaminant ...

Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium

quantification of active pharmaceutical ingredients (API s) potentially present in these suspicious SF antimicrobials, are paramount. Here, a validated ultra-high performance liquid chromatography-tandem mass ...

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 ...

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

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 MOAH concentrations ...

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 ...

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- ...
