The occurrence of putative cognitive enhancing research peptides in seized pharmaceutical preparations: An incentive for controlling agencies to prepare for future encounters of the kind.
served as an incentive to develop a novel combined liquid chromatography tandem mass spectroscopy (LC- MS / MS) methodology, applicable to both hydrophilic or more hydrophobic peptides, which was utilized ...
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 ...

Analysis of mineral oil in food: An analytical challenge
Gas Chromatography (LC- GC) with Flame Ionization Detection (FID) is used for quantification of MOSH and MOAH. However, due to the limited availability and applications of this instrumentation, another ...
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

A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies
chromatography with UV-detection for the screening of five regulated plants used in respectively dietary supplements for slimming and potency enhancement. Both types of fingerprints are combined with chemometric ...
Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
Keywords: Dried herbs gas chromatography Mass Spectrometry PAHs Spices Abstract: This paper describes a method for quantification of the four regulated polycyclic aromatic hydrocarbons (PAH ...
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 ...
