Article Synopsis
- A novel method using TurborFlow online solid phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed for screening and confirming 88 veterinary drugs in milk from various families, achieving results in under 39 minutes.
- The method includes sample dilution and ultrasonic extraction, followed by automated clean-up and detection using selected reaction monitoring mode (SRM), and has shown high reliability with R(2) values above 0.9930.
- Validation results show limits of detection as low as 0.2-2.0 μg/kg, and overall recovery rates for spiked compounds range from 63.1% to 117.4%, demonstrating its effectiveness and potential
A confirmatory and quantitative method based on liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) has been developed for simultaneous determination of 13 aminoglycoside antibiotics in various samples. The aminoglycoside analytes were released and extracted from different matrices with 5% trichloroacetic acid. The influence of pH values on the solid-phase exaction (SPE) procedure has been studied.
