And the article contained the following:
The aim of this study was to develop a UHPLC-HRMS methodol. as a suitable tool for the screening of antibiotics in milk, fresh cheese, and whey. Compounds were analyzed using an Orbitrap Exactive analyzer working at a resolving power of 50,000 FWHM in full scan, both in pos. and neg. electrospray ionization mode, and a high mass accuracy (<5 ppm) and a retention time deviation of ±2.5% were set as identification criteria. The multiclass method was developed for the simultaneous determination of 36 substances from different antibiotic groups (β-lactams, lincosamides, macrolides, quinolones, sulfonamides, and tetracyclines) and the quantification was performed by using matrix-matched calibration curves corrected by the corresponding internal standards Matrix effect and recovery percentages were also calculated prior to the selection of internal standard After comparing different sample preparation procedures, a quick and easy extraction with acetate buffer at pH 5.2 and acetonitrile (20/80, volume/volume), followed by C18 dispersive Solid Phase Extraction (dSPE) bulk sorbent was selected. The detection capabilities (CCβs) were established at 25% or 50% of the Maximum Residue Limit (MRL) set in milk (no regulation for cheese and whey), and precision (repeatability and reproducibility) and trueness (recovery) were satisfactory according to Commission Decision 2002/657/EC. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Computed Properties of 144-80-9
