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.
to mass spectrometry (MS) in electron ionisation mode was used to identify migrants through spectral library matching. When no acceptable match was obtained, a second analysis by GC ...
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, ...

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 ...
