Rapid Determination of Sulfathiazole, Oxytetracycline and Tetracycline in Honey by High-Performance Liquid Chromatography
TLDR
In this article, a simple, rapid and precise analytical method for sulfathiazole, oxytetracycline and tetracecline residues in honey has been established using micellar reversed-phase high-performance liquid chromatography with photometric detection.Abstract:
A simple, rapid and precise analytical method for sulfathiazole, oxytetracycline and tetracycline residues in honey has been established using micellar reversed-phase high-performance liquid chromatography with photometric detection. The mean recoveries of sulfathiazole, oxytetracycline and tetracycline were 97.7, 95.3 and 100.4%, respectively. Detection limits in honey were 0.9 μg/g for sulfathiazole, 1.2 μg/g for oxytetracycline and 3.0 μg/g for tetracycline.read more

Liquid chromatography with ultraviolet absorbance detection for the analysis of tetracycline residues in honey
TL;DR: The separation of tetracyclines (TCs) using reversed-phase liquid chromatography (LC) using an amide-based stationary phase prevents the interaction with the residual silanol groups and thus avoids the appearance of tailed peaks.

Determination of tetracycline antibiotics in tissues and blood serum of cattle and swine by high-performance liquid chromatography.
TL;DR: Tissue homogenates and blood serum were acidified with hydrochloric acid and deproteinized with acetonitrile and recovered near 100% from blood serum, 83-94% from muscle, and 80-100% from liver and kidney with sensitivities of 0.1 ppm or less for muscle andBlood serum.
