Featured Application: Multiclass Veterinary Antibiotics on Raptor C8 by LC- One Analysis, One Column, Less than 9 Minutes for Over 0 Multiclass Antibiotics Highly efficient peak separation and fast analysis times. Versatility and global applicability for antibiotic residue analysis capable of individual class panel optimization for quantitation: - Macrolide, Lincosamide, and Streptogramin (Figure ) - Amphenicol and Tetracycline (Figure ) - Quinolone (Figure ) - Penicillin, Cephalosporin, and Tetracycline (Figure 4) - Sulfonamide (Figure 5) (For Ionophore, use on Raptor Biphenyl. [Figure ]) The use of antibiotics on food-producing animals is a public health and safety concern due to the potential of generating drug-resistant bacteria. Many countries in the European Union and Canada have banned the use of antibiotics for nontherapeutic purposes, and the United States is implementing a policy to reduce the use of medically important antibiotics for growth promotion. To regulate the proper use of veterinary antibiotics, the U.S. FDA has set maximum residue limits (MRL) for a variety of animal tissue and food products ( CFR Part 55). A sensitive, efficient, and reliable analytical method for different classes of antibiotics is necessary to meet this regulation, and the Raptor C8 LC column is the ideal choice..
