Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
119 (2021) Keywords: Chlorinated alkanes chlorinated paraffins food gas chromatography Mass Spectrometry Abstract: This work describes the optimization and validation of an analytical method for the ...
Analysis of mineral oil in food: An analytical challenge
matrix has also an important impact, not only on data integration and interpretation but also on the sample preparation. Due to the presence of olefins and natural alkanes, some matrices require auxiliary ...
PKC epsilon-dependent calcium oscillations associated with metabotropic glutamate receptor 5 prevent agonist-mediated receptor desensitization in astrocytes.

Study of the possible migration risks of food contact materials for children under 3 years
MS performing an untargeted database search using Wiley® and NIST ® libraries. Although the concentrations observed were rather low, various compounds, such as alkanes, phthalates, amides, etc. were ...
Development and application of a non-target extraction method for the analysis of migrating compounds from plastic baby bottles by GC-MS.
of migrants, though sometimes in relatively large amounts. Alkanes (especially in polypropylene (PP) bottles), phthalates (dibutylphthalate in one PP bottle and one silicone bottle; diisobutylphthalate ...
Development and application of a non-targeted extraction method for the analysis of migrating compounds from plastic baby bottles by GC-MS.
variety of migrating compounds, whereas PES and polyamide (PA) showed a lower amount of migrants, though sometimes in relatively large concentrations (azacyclotridecan-2-one up to 250 µg kg⁻¹). Alkanes ...
Carbon source-induced modifications in the mycolic acid content and cell wall permeability of Rhodococcus erythropolis E1.
alkane-degrading strain of Rhodococcus erythropolis (strain E1), with particular focus on the mycolic acid content. A clear correlation was observed between the carbon source and the mycolic acid profiles as ...
Influence of the growth substrate on the mycolic acid profiles of mycobacteria.
Mycobacterium spp. LB501T, LB307T and VM552 was examined by high-performance liquid chromatography (HPLC) using glucose, alkanes, polycyclic aromatic hydrocarbons (PAH) or Luria-Bertani medium (LB) as the sole ...
