Analysis of Polyether Antibiotics in Animal Feeds Using Fluorescence Detection

User Benefits

- The feed additive lasalocid sodium can be analyzed with good repeatability over a wide range of concentrations in accordance with "Feed Analysis Standards". - Rapid analysis can be performed with easy operation compared to the microbiological quantification method listed in "Feed Analysis Standards". - Significant labor-saving and improved efficiency of analytical procedure can be achieved by automated entire analytical process from instrument startup to shutdown.

Introduction

Polyether antibiotics are designated as feed additives in accordance with the Public Notice No.750 by the Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF). For the analytical methods of these antibiotic components, microbiological quantification, HPLC, and LC/MS methods are specified in "Feed Analysis Standards," the Notice by the Director-General, Food Safety and Consumer Affairs Bureau, MAFF. However, the microbiological quantification method requires a long time to obtain results due to the complicated process of test organism storage and culture media preparation, along with 16 to 24 hours of cultivation. On the other hand, HPLC method can provide rapid analysis because it does not use microbes that require long term storage and/or cultivation. In this article, we introduce a analysis of lasalocid sodium, for which the fluorescence detection method is specified.
