Analysis of Residual Antimicrobials in Meat Using HPLC

Analysis of residual antimicrobials in animal products is crucially important to ensure food safety. This article presents a simple, fast, and highly sensitive high performance liquid chromatography (HPLC) assay of regulated antimicrobials, as well as sample preparation and purification methods. Twenty-four different analytes of interest were investigated in beef, pork, and chicken meat samples.

Equine Drug Testing with LC–MS/MS

Doping and cheating the competition may be as old as competition itself. Doping horses for chariot racing was reported during the Roman Empire and doping is now commonly reported in the press. Advanced technologies such as ultrahigh-pressure liquid chromatography (UHPLC) analysis coupled to ultrafast tandem mass spectrometry (MS/MS) detection provide excellent sensitivity for the analysis of horse doping agents.

Extraction and Quantification of Mycotoxins in Peanut Butter Using SFE–SFC–MS

Aflatoxins are poisonous and carcinogenic chemicals that occur in nature in soil, hay, and grains. When contaminated food is processed, aflatoxins can enter the general food supply chain and can be dangerous for humans and animals. Time- and cost-efficient analytical methods can ensure food safety. Compared to conventional manual methods the use of “supercritical” CO2 for supercritical fluid extraction (SFE) as well as chromatographic separation (supercritical fluid chromatography [SFC]) of aflatoxins offers a more efficient process while reducing solvent consumption.
