Slight differences in BGE composition which we propose for the analysis of organic acids can result in simultaneous determination of some other important components like inorganic anions,antioxidants,preservatives *** BGE,which we normally use for the analysis of major inorganic cations,is also well suited for the determination of biogenic amines after just a very slight ***,the same buffer enables to determine simultaneously a variety of aliphatic amines and some amino *** overall CE-profiles of wine or wine product become highly informative because of the quantitative information about the numerous accompanying(especially minor)components.

A simple,sensitive and reliable analytical method was developed for the simultaneous determination38 veterinary drugs(18 sulfonamides,11 quinolones and 9 benzimidazoles) and 8 metabolites of benzimidazoles in bovine milk by ultra high performance liquid chromatography-positive electrospray ionization tandem mass spectrometry(UHPLC-ESI-MS/MS).Samples were extracted with acidified acetonitrile,cleaned up with Oasis MCX cartridges,and analyzed by LC-MS/MS on an Acquity UPLCBEH C18 column with gradient *** method allows such multi-analyte measurements within a13 minute runtime while the specificity is ensured through the MRM acquisition *** method was validated according to the European Commission Decision 2002/657/EC determining specificity,decision limit(CC α),detection capability(CC α),recovery,precision,linearity and *** compounds which have MRLs in bovine milk,the CC α values fall into a range from 11 to 115 μ g/kg,and the CC P values fall within a range of 12 to 125 μ g/*** compounds which have not MRLs in bovine milk,the CC αvalues fall into a range from 0.01 to 0.08 μ g/kg,and the CC 3 values fall within a range of 0.02 to 0.11μg/*** mean recoveries of the 46 analytes were between 87 and 119%.The calculated RSD values of repeatability and within-laboratory reproducibility experiments were below 11%and 15%for the 46compounds,*** method is demonstrated to be suitable for the simultaneous determination of sulfonamides,quinolones and benzimidazoles in bovine milk.
