Foreword

This standard replaces GB/T 8381.7-2005 "Determination of Olaquindox in Feed by High Performance Liquid Chromatography". The main changes in this standard compared with GB/T 8381.7-2005 are as follows. In the sample extraction process increased the solid phase extraction purification method, the mobile phase is no longer pH adjustment. This standard is proposed and assigned by the National Committee for Standardization of Feed Industry (SAC/TC76). This standard is responsible for the drafting unit. Ministry of Agriculture feed industry center, the Ministry of Agriculture feed efficiency and safety supervision and testing center (Beijing), China Agricultural University. The main drafters of this standard. Yang Wenjun, Zhang Liying, Wang Zongyi, He Pingli. This standard replaced the previous version of the standard release. --- GB/T 8381.7-2005. Determination of Olaquindox in Feed High performance liquid chromatography

1 Scope

This standard specifies the method for the determination of olaquindox in feed by high performance liquid chromatography (HPLC). This standard is applicable to the determination of olaquindox in mixed feed, concentrated feed and additive premix feed with a minimum limit of 1 mg/kg, The detection limit was 0.1 mg/kg.
