This document introduces an antibiotic called Lasalocid, which belongs to a group of antibiotics known as ionophores and can be used in the prophylaxis and treatment of coccidiosis and leukocytozoonosis in poultry. The document focuses on the ability of the Varian 320-MS Triple Quadrupole Mass Spectrometer to detect Lasalocid in animal feed.
This document details the detection of lasalocid, an ionophore antibiotic, in animal feed extracts using the Agilent 320-MS Triple Quadrupole Mass Spectrometer. The study demonstrates the instrument's ability to detect the substance with good reproducibility in both positive and negative ionization modes.
