Quinolones, including fluoroquinolones, are a group of synthetic antibacterial compounds used in the treatment of several diseases. The presence of these compounds is an indication of unsafe practices of food production and deficient methods in the production of honey. We developed a sensitive and reproducible LC-MS/MS method for the quantitation of 12 fluoroquinolones and 4 quinolones in honey using automated extraction by TurboFlow technology as an alternative to the commonly used, time-consuming solid-phase extraction (SPE) method.

To provide an application for the analysis of fluoroquinolones using the Thermo Scientific™ Hypersil GOLD VANQUISH™ 1.9 µm column and Thermo Scientific™ Vanquish H™ UHPLC system

Antibiotics are widely used to treat diseased animals, prevent diseases and promote growth. However, inappropriate or excessive usage of antibiotics can result in antibiotic residues being found found in food and food products of animal origin. In here, a multi-residue, confirmatory method for the quantitative determination of antibiotics in chicken meat is described using the Thermo Scientific Transcend TLX system coupled to an LC-MS/MS. With online sample cleanup and high sample throughput, this approach addresses the demand for a fast and cost-effective multi-analyte method.

The use of LC-MS/MS for screening was described in a validated multi-residue screening method to monitor 58 antibiotics in milk.
