Description of BS EN 17270:2019 2019This document specifies a test method for the determination of theobromine in feed material or compound feed in the working range 27Â mg/kg to 307Â mg/kg using liquid chromatography coupled to a UV detector (HPLC-UV) or in the working range 49Â mg/kg to 307Â mg/kg using liquid chromatography with tandem mass spectrometry (LC-MS/MS). This method has been fully validated using complementary compound feed for adult dogs and complementary compound feed for horses. This method is also considered applicable for determining theobromine in baking chocolate using either HPLC-UV or LC-MS/MS systems. The working range can be extended provided the extended range is validated.
