AN353: Rapid Determination of Sulfonamide Residues in Animal Tissue and Infant Food Containing Animal Products Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

Veterinary drugs containing antimicrobial agents are often administered to livestock to treat or prevent disease and, at low levels, to promote growth in food-producing animals. Government agencies have discovered that some companies are abusing the use of these drugs, by administering them at higher than recommended levels to promote faster growth. This practice results in unwanted drug residues in meat and meat products eaten by humans. Sulfonamides are one class of antimicrobial agent used for that purpose. This AN shows that ASE can extract sulfonamides from meat and baby food with meat.

AN330: Accelerated Solvent Extraction (ASE) of the Organic Components of Granular and Liquid Detergents

Instrument Type: Automated Sample Prep

Organic solvent extraction is a standard technique in the detergent industry for isolation of organic components from inorganic matrices and separation of ionic and nonionic surfactants. For example, analysis of the alcohol-soluble portion of detergents is routinely performed to verify the integrity of the manufacturing process. Traditional extraction of this material is labor-intensive and uses large amounts of liquid solvent. With ASE, manufacturers can streamline the extraction process to quickly verify product quality and provide feedback information into the production cycle.
