LC-HRMS analysis of phospholipids bearing oxylipins

Analytica Chimica Acta
Several oxylipins including hydroxy- and epoxy-polyunsaturated fatty acids act as lipid mediators. In biological samples they can be present as non-esterified form, but the major part occurs esterified in phospholipids (PL) or other lipids. Esterified oxylipins are quantified indirectly after alkaline hydrolysis as non-esterified oxylipins. However, in

Combining LC-HRMS and LC-HRMS/MS data to explore a cereal food processed under different conditions

Characterizing the chemical fingerprint of a processed food is a major challenge to advance food quality. New untargeted approaches based on LC-HRMS analysis can unlock the potential to increase our understanding on how chemical components, linked to different food quality dimensions, react and evolve during the manufacturing processes and thus ...

Multiplex Detection of 24 Staphylococcal Enterotoxins in Culture Supernatant Using Liquid Chromatography Coupled to High-Resolution Mass Spectrometry

Toxins, 2022
Staphylococcal food poisoning outbreaks are caused by the ingestion of food contaminated with staphylococcal enterotoxins (SEs). Among the 27 SEs described in the literature to date, only a few can be detected using immuno-enzymatic-based methods that ...

Characterization of an Amphetamine Interference from Gabapentin in an LC–HRMS Method [PDF]

Journal of Analytical Toxicology, 2019
Abstract An amphetamine interference was observed during the development of an liquid chromatography–high-resolution mass spectrometry (LC–HRMS) multi-class confirmation method for the determination of 47 drugs and metabolites in urine. The interference passed all qualitative criteria for amphetamine leading to potential false-positive ...

Rapid and Reliable Data Treatment for the Control of Food Chemical Contaminants by LC-HRMS

, 2022
Liquid chromatography-high resolution mass spectrometry (LC-HRMS) is considered an unavoidable extension of low-resolution LC-MS/MS that stretches the capabilities of multi-residue analysis of chemical contaminants in food.

Extending the Lipidome Coverage by Combining Different Mass Spectrometric Platforms: An Innovative Strategy to Answer Chemical Food Safety Issues

Foods, 2021
From a general public health perspective, a strategy combining non-targeted and targeted lipidomics MS-based approaches is proposed to identify disrupted patterns in serum lipidome upon growth promoter treatment in pigs.

Ammonium Fluoride as Suitable Additive for HILIC-Based LC-HRMS Metabolomics [PDF]

Metabolites, 2019
Hydrophilic Interaction Liquid Chromatography (HILIC) chromatography is widely applied in metabolomics as a complementary strategy to reverse phase chromatography. Nevertheless, it still faces several issues in terms of peak shape and compounds ionization, limiting the automatic de-convolution and data semi-quantification performed through dedicated ...
