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 ...

Physicochemical characterisation of several types of the E171 food additive

IMEKOFOODS 4 (2019) URL: https://www.imekofoods4.be/ Keywords: Characterization E171 electron microscopy particle size distributions. single particle inductively coupled plasma mass spectroscopy titanium oxide ...

Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products

for validated methods to size and quantify these particles. Single particle inductively coupled plasma-mass spectrometry (spICP- MS) is thereby a promising technique as it is capable of sizing and ...

Species Distinction in the Trichophyton rubrum Complex.

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 the species ...

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 ...

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 ...

Physicochemical Characterisation of the E171 Food Additive

on the physicochemical characterization of 15 pristine E171 materials by transmission electron microscopy (TEM) and single particle inductively coupled plasma mass spectroscopy (sp- ICP- MS) following ...

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- ...

Human urine contamination with environmental pollutants: simultaneous determination using UPLC-MS/MS

determine three paraben derivatives: methylparaben (MP), ethylparaben (EP) and propylparaben (PP) using ultra performance liquid chromatography-tandem mass spectrometer (UPLC- MS / MS). The three major ...
