Abstract
A fast method of screening of samples and determination of 80 veterinary drug residues in food safety assessment is proposed. The stage of solid-phase extraction for the purification of the extract in the sample preparation is excluded; here, the matrix effect is neutralized by using isotope-labeled standards. The application of the isotope dilution method makes it possible to exclude the stage of construction of matrix calibration curves and to calculate the concentrations using correction coefficients found from standard aqueous solutions of analytes with a limited number of isotope-labeled standards (one standard each for each class of compounds under determination). The limits of detection of medicinal products (cmin = 0.1–10 ng/g) make it possible to determine their residues at the level of maximum allowable concentrations for food.
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
