Evaluation of the migration of chemicals from baby bottles under standardised and duration testing conditions.
toxicity assessment, the most toxic migrating compounds were selected to be monitored and quantified using validated GC- and LC-QqQ- MS methods. The effect of several ‘real-life-use conditions’, such as ...
Determination of halogenated flame retardants in food: optimization and validation of a method based on a two-step clean-up and gas chromatography-mass spectrometry
basket gas-chromatography-mass spectrometry (GC-MS) Meat method milk Mode ON PBDEs performance Sample Samples silica Target TBA Type VALIDATION Weight work Abstract: In this work, a new simple method based ...
Quantitative Determination of Migrating compounds from Plastic Baby Bottles by Validated GC-QqQ-MS and LC-QqQ-MS Methods
Volume 9 (2016) Keywords: Baby bottles Bisphenol A (BPA) alternatives food contact materials GC/LC-QqQ-MS Migration Abstract: Following the recent prohibition on the use of BPA for the production of ...
Identification of substances migrating from plastic baby bottles using a combination of low-resolution and high-resolution mass spectrometric analysers coupled to gas and liquid chromatography.
a strategy for elucidation of unknown migrants from plastic food contact materials (baby bottles) using a combination of analytical techniques in an untargeted approach. First, gas chromatography (GC) coupled ...
Travelling-wave ion mobility time-of-flight mass spectrometry as an alternative strategy for screening of multi-class pesticides in fruits and vegetables.
parameter for identification purpose. This 2% value is in agreement with already reported criteria, for instance, for GC or LC retention time in European documents. Finally, the well-known feature of mobility ...
Rapid Determination of Ethephon in Grapes by Hydrophilic Interaction Chromatography Tandem Mass Spectrometry
Spectrometry time Abstract: Ethephon analysis usually requires indirect and laborious method including a derivatization step before gas chromatography tandem mass spectrometry (GC- MS / MS) determination. In ...
The search for therapeutic bacteriophages uncovers one new subfamily and two new genera of Pseudomonas-infecting Myoviridae.
differences in genome size, % GC and genomic contents, as well as number of tRNAs. These two clades are well delineated, with a mean of 86% and 92% of proteins considered homologous within individual clades, ...
Development and application of a non-target extraction method for the analysis of migrating compounds from plastic baby bottles by GC-MS.

HS-GC-MS method for the analysis of fragrance allergens in complex cosmetic matrices.
combined with a new headspace GC- MS method. The latter was capable of analysing 24 volatile allergenic fragrances in complex cosmetic formulations, such as hydrophilic (O/W) and lipophilic (W/O) creams, ...
Development and application of a non-targeted extraction method for the analysis of migrating compounds from plastic baby bottles by GC-MS.
a liquid-liquid extraction followed by GC / MS analysis. A 50% EtOH in water solution was selected as a simulant for milk. After sterilisation of the bottle, three migration experiments were performed during 2 h at ...
