Fabric phase sorptive extraction of selected penicillin antibiotic residues from intact milk followed by high performance liquid chromatography with diode array detection
Rapid fabric phase sorptive extraction (FPSE) was applied for penicillins in milk. Protein precipitation was eliminated from the sample preparation work-flow. FPSE simplified sample preparation without sacrificing quality of analytical data. Model driven sorbent selection strategy led to correct phase without experimentation. Robust FPSE sample preparation could be adopted as convenient routine QC practice.
