Various extraction methods for the simultaneous determination of veterinary drugs in several matrices by UHPLC–MS–MS are described.
Various extraction methods for the simultaneous determination of veterinary drugs in several matrices (milk, egg and honey) by ultra high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC–MS–MS) are described. The following extraction techniques have been used: solvent extraction, solid-phase extraction (SPE) and modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe). The three proposed methods are validated and the advantages and disadvantages of them are outlined.
Emerging Trends and Challenges in Detecting Residues and Contaminants in Food in the Exposome Era
June 18th 2025This article describes the analytical challenges of chemical exposomics in food safety. The need for high-throughput, multi-platform approaches—such as LC–HRMS and GC–HRMS with IMS—to capture the full spectrum of potential contaminants in our food supply is emphasised.
New Research Explores Role of Nucleotide Hydrophobicity in Oligonucleotide Separation
June 18th 2025Researchers from Waters and Biospring studied the contribution of nucleotide type and modifications on the retention and resolution of 22–24 nt long oligonucleotides in different chromatographic methods.
