Animal feeding stuffs - Determination of decoquinate by HPLC with fluorescence detection
 N EN 16162

Annotation

This European Standard specifies a method for the determination of decoquinate. This high-performance liquid chromatographic (HPLC) method with a fluorescence detection is applicable to the quantification of decoquinate content in complete and complementary compound feeds, medicated feeds, semi-liquid feeds, premixtures and feed additives.

The method was fully validated from LOQ to 60 000 mg/kg on different matrices during an international collaborative study, especially on complete compound feeds for poultry, at trace contamination level of 3 mg/kg and at European authorized level of 20 mg/kg to 40 mg/kg.

The limit of detection is between 0,1 mg/kg and 0,3 mg/kg and the limit of quantification is around 0,5 mg/kg. These limits were validated during the collaborative study, from results on the blank feed. Lower limits of detection or quantification could be reached but a single laboratory validation is then requested.

Кормы животных - Определение decoquinate HPLC с обнаружением флуоресценции

Этот европейский стандарт определяет метод для определения decoquinate. Этот метод высокоэффективной хроматографической жидкости (HPLC) с обнаружением флуоресценции применим к определению количества decoquinate содержания в полных и дополнительных комбикормах, содержащем лекарственное вещество корме, полужидком корме, предварительных смесях и добавках подачи.
