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.
Most current methodologies for the quantitation of antibiotics in drinking water revolve around analysis using triple stage quadrupole platforms with offline sample preparation. This is a proven technique for the analysis of many contaminants in various types of water samples, but the offline sample preparation steps are time-consuming and prone to operator error and reproducibility problems. We demonstrate the ability to directly inject the water sample without any offline preconcentration. We utilize LC-MS with a Thermo Scientific Exactive Plus Orbitrap MS using HR/AM.
Veterinary drugs are pharmacologically active compounds that can result in non-desirable drug residues in the food chain. Animals with high amounts of these drugs can cause harm in humans or can render the use of antibiotics useless due to the counter effects of the drugs. The quantification of over 200 multi-class veterinary drugs from different meat products usually involves time consuming extraction methods with either SPE or LLE. We describe a robust method, utilizing a single LC-MS/MS run to quantitate over 200 veterinary drugs in a variety of matrices.
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.
This application shows the advantages of using the Thermo Scientific™ Hypersil GOLD aQ VANQUISH™ 1.9 µm column and Thermo Scientific™ Vanquish™ UHPLC system, for the fast analysis of sulfur-containing drugs. The built-in method scaling of the Chromeleon software and high pressure capabilities of the Hypersil GOLD VANQUISH columns, that allow operation at higher flow rates,enable the development of rapid analytical methods whilst maintaining high performance.
