HPTLC of 81 veterinary drugs from 6 different groups (glucocorticoids, anthelmintics, antiparasitics, coccidiostats, nonsteroidal anti-inflammatory drugs, and antibiotics) in 4 different matrices (honey, pig muscle, cow milk, and chicken eggs) on silica gel with acetonitrile - ammonia - ethanol 13:4:3 up to 80 mm and then in the reverse direction with methanol - acetonitrile - ethanol - ammonia 6:2:1:1 up to 45 mm. After each step, the plates were automatically dried in a cold stream of air for 3 min. Detection under UV light at 254 nm and fluorescence light detection (FLD) at 366 nm. Zones were eluted from the plate using a fully automated auto TLC-LC-MS interface for further analysis by high-resolution tandem mass spectrometry. Most veterinary drugs except penicillins and cephalosporins were detected at the 5 μg/kg level in pig muscle, cow milk, and chicken eggs and 25 μg/kg level in honey.
