Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.

products by transmission electron microscopy (TEM) and single-particle inductively coupled plasma-mass spectrometry (spICP- MS). TEM analysis showed that all samples contained micrometre-sized flakes and ...

Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.

standardized and validated methodologies to characterize representative samples of 15 pristine E171 materials based on transmission electron microscopy (TEM) and single-particle inductively coupled plasma mass ...

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.

recommendation paper of the General European Official Medicines Control Laboratory (OMCL) network on the interpretation of screening results for unknown peptides by mass spectrometry, was also validated in ...

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 ...

Species Distinction in the Trichophyton rubrum Complex.

matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI- TOF MS) and amplified fragment length polymorphism (AFLP) were partially consistent with the ITS data but failed to distinguish ...

Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.

plasma mass spectrometry (spICP- MS) method was developed and validated for sizing and quantifying the fraction of AgNP in E174 and in products containing E174, and associated uncertainties related to ...

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 ...
