Studies from Warsaw University of Technology Have Provided New Data on Sulfones [Multiresidue analysis of 22 sulfonamides and their metabolites in animal tissues using quick, easy, cheap, effective, rugged, and safe extraction and high ...]

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Sulfones have been published. According to news reporting out of Warsaw, Poland, by NewsRx editors, research stated, "A new high performance liquid chromatography-high resolution mass spectrometry (HPLC-HRMS) method was developed for a simultaneous multi-residue analysis of 22 sulfonamides (SAs) and their metabolites in edible animal (pig, beef, sheep and chicken) tissues. Sample preparation was optimized on the basis of the 'QuEChERS' protocol."

Our news journalists obtained a quote from the research from the Warsaw University of Technology, "The analytes were identified using their LC retention times and accurate mass; the identification was further confirmed by multi-stage high mass accuracy (

According to the news editors, the research concluded: "The method was applied to various matrices (kidney, liver, muscle) originated from pig, beef, sheep, and chicken) allowing the simultaneous quantification of target sulfonamides at concentration levels above the MRL/2 and the identification of untargeted compounds such as N-4-acetyl metabolites using multi-stage high mass accuracy mass spectrometry."
