Scope

Scope: This document specifies a method for determining the content of betaine (or hydrochloride) in compound feed, concentrated feed, premix feed, and feed additives using high-performance liquid chromatography (HPLC). This document is applicable to the determination of the content of betaine (or hydrochloride) in compound feed, concentrated feed, premix feed, and feed additives; Main technical content: The betaine in the sample is extracted by ultrasonic treatment in water, and the solution is subjected to liquid-liquid extraction. After the extract is diluted to a suitable concentration, the determination is carried out using HPLC, with external standard quantification.
