HILIC-MS and CE-MS as complementary analytical approaches to assess the impact of exposure to polychlorinated biphenyls on the polar serum metabolome of pigs.

Posted on 7 October, 2024 by fqm302

Hydrophilic interaction liquid chromatography (HILIC) and capillary electrophoresis (CE) coupled to mass spectrometry (MS) are two of the most widely used techniques to explore and characterize the polar metabolome. Both platforms have some peculiar characteristics that make them more suitable … Continue reading →

A comparison of hydrophilic interaction liquid chromatography and capillary electrophoresis for the metabolomics analysis of human serum.

Posted on 6 August, 2023 by fqm302

Cationic, anionic, zwitterionic and, partially polar metabolites are very important constituents of blood serum. Several of these metabolites underpin the core metabolism of cells (e.g., Krebs cycle, urea cycle, proteins synthesis, etc.), while others might be considered ancillary but still … Continue reading →

Determination of multiclass cyanotoxins in blue-green algae (BGA) dietary supplements using hydrophilic interaction liquid chromatography-tandem mass spectrometry.

Posted on 7 February, 2023 by fqm302

In recent years, the consumption of blue-green algae (BGA) dietary supplements is increasing because of their health benefits. However, cyanobacteria can produce cyanotoxins, which present serious health risks. In this work we propose hydrophilic interaction liquid chromatography coupled with tandem … Continue reading →
