Antibiotics Residues in Milk Analyzed via QuEChERS and LC-MS/MS

91 real milk samples were analyzed for three antibiotics using an optimized QuEChERS extraction method and ultra-performance liquid chromatography-tandem mass spectrometry. The method achieved recoveries from 95 to 99%, linearity (R2) above 0.96, and limits of detection between 1.4-6.8 µg L-1. This research dataset was contributed by Andressa Grabsk via the paperswithcode platform.

Use Cases

• Validate analytical methods for antibiotic detection in dairy based on described recovery and precision metrics.
• Train machine learning models for predicting extraction efficiency based on clean-up variables like C18, PSA, and NaAc.
• Benchmark performance of QuEChERS protocols for specific compounds like ceftiofur, cloxacillin, and enrofloxacin.

Strengths

• Method validation includes specific performance metrics: recoveries of 95-99% and linearity R2 > 0.96.
• Precision is documented with intraday relative standard deviations lower than 12.3%.
• Applicability is demonstrated using 91 real-world milk samples.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
