Technical Note: Antibiotics Analysis bij HPLC

Antibiotics are widely used in food-producing animals to prevent disease or promote growth. The use of antibiotics may result in drug residues in the animal-derived food. The analysis of antibiotics residues in animal-derived food is important worldwide to ensure foods safety. Excellent High Performance Liquid Chromatography (HPLC) analyses of these substances can be achieved by using COSMOSIL columns.
