The selectivity of mass traces obtained by monitoring liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS) and liquid chromatography coupled to tandem mass spectrometry(More)
A quantitative multiresidue method covering more than 100 veterinary drugs, belonging to different drug families, has been developed. The proposed approach uses an liquid-liquid-solid extraction(More)
In pesticide residue analysis using liquid chromatography/tandem mass spectrometry (LC/MS/MS) the confirmation of a sebuthylazine finding in a tarragon (Artemisia dranunculus) sample was demonstrated(More)
The quantitative and confirmative performance of two different mass spectrometry (MS) techniques (high-resolution MS and tandem MS) was critically compared. Evaluated was a new extraction and(More)
The use of chloramphenicol (CAP)--a highly effective broad-spectrum antibiotic used in animal husbandry--is banned in many countries. Therefore, a very low minimum required performance limit (MRPL)(More)
