Animal feeding stuffs. Methods of sampling and analysis. Determination of benzoic and sorbic acid by High Performance Liquid Chromatography (HPLC) Ingestion-build-48024 e) wood based panel products1 Scope This document specifies a method for the determination of benzoic acid and sorbic acid in animal feeding stuffs by high performance liquid chromatography method with ultraviolet detection (HPLC UV). The method is intended to be used for the determination of benzoic acid and sorbic acid as active substances in feed additives, premixtures, feed materials and compound feed and for benzoic acid in water. This method determines the total
