Abstract
This article describes the development of a technique for the determination of fat-soluble vitamins using high-performance liquid chromatography with mass spectrometric detection in feed, feed additives. Measurement ranges of mass concentrations of vitamins: A—from 0.35–14.0 mg/kg, D3—from 0.0065–1.0 mg/kg, and E—from 0.63–50.0 mg/kg. The technique is based on alkaline hydrolysis of the sample and extraction of fat-soluble vitamins with hexane. The analysis of the obtained extracts is carried out by high-performance liquid chromatography with mass spectrometric detection (HPLC MS/MS).
期刊介绍：
Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
