The VetDrugs Explorer Collection: screening and quantitation of multi-class veterinary drug residues in animal matrices with a comprehensive workflow solution

Instrument Type: LCMSMS

A robust, sensitive, and reliable multi-residue LC-MS/MS method workflow solution that uses the Thermo Scientific TSQ Altis triple quadrupole mass spectrometer provides analysis and quantitation of more than 160 veterinary drugs with the Thermo Scientific VetDrugs Explorer Collection solution in salmon (fillet), bovine muscle, and milk. The complete instrument and data processing method including SRM settings is included with the VetDrugs Explorer Collection start-to-finish workflow solution. In 17 minutes, the target veterinary drugs were detected and quantified in food matrices.

Analysis of (Fluoro)quinolones in Honey with Online Sample Extraction and LC-MS/MS

Instrument Type: LCMSMS

Quinolones, including fluoroquinolones, are a group of synthetic antibacterial compounds used in the treatment of several diseases. The presence of these compounds is an indication of unsafe practices of food production and deficient methods in the production of honey. We developed a sensitive and reproducible LC-MS/MS method for the quantitation of 12 fluoroquinolones and 4 quinolones in honey using automated extraction by TurboFlow technology as an alternative to the commonly used, time-consuming solid-phase extraction (SPE) method.

Quantification of EPA 1694 Pharmaceuticals and Personal Care Products in Water at the ng/L Level Utilizing Online Sample Preparation with LC-MS/MS

Instrument Type: LCMSMS

There is growing environmental concern regarding the health impact of trace levels of pharmaceuticals and personal care products (PPCPs) in water resources. In response, the U.S. Environmental Protection Agency (EPA) published Method 1694, which determines dozens of PPCPs in water, soil, sediment, and biosolids by HPLC-MS/MS. We demonstrate a progressive approach to analyzing PPCPs in environmental sources of water at the ng/L level with online sample preparation using small volumes of water, thus saving time and reducing the cost of analysis.

Automated Online Multi-Residue LC-MS/MS Method for the Determination of Antibiotics in Chicken Meat

Instrument Type: LCMSMS

Antibiotics are widely used to treat diseased animals, prevent diseases and promote growth. However, inappropriate or excessive usage of antibiotics can result in antibiotic residues being found found in food and food products of animal origin. In here, a multi-residue, confirmatory method for the quantitative determination of antibiotics in chicken meat is described using the Thermo Scientific Transcend TLX system coupled to an LC-MS/MS. With online sample cleanup and high sample throughput, this approach addresses the demand for a fast and cost-effective multi-analyte method.

Multi-residue Automated Turbulent Flow Online LC-MS/MS Method for the Determination of Antibiotics in Milk

Instrument Type: LCMSMS

The use of LC-MS/MS for screening was described in a validated multi-residue screening method to monitor 58 antibiotics in milk.
