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 ...

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
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 bisphenols (BP) (BPA, ...
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 ...
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- ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
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 bisphenols (BP) (BPA, ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
a screening and a quantification method using ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC- MS) and diode array detection (UHPLC- DAD), respectively were developed and ...
