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.

Advances in Automation of Food-related Analysis and Screening

Instrument Type: LCMSMS

Worldwide food safety concerns have risen dramatically as the number of food contamination incidents and product recalls has increased. Every food analysis starts with sample preparation, which is widely accepted as one of the most critical steps of LC/MS. Increased demand for higher throughput, accuracy and lower matrix interference from food analysis laboratories has made sample preparation the largest bottleneck. Turbulent flow chromatography technology can eliminate the need for lengthy offline sample preparation steps, thereby eliminating these disadvantages.

High Resolution LC-MS for Screening and Quantitative Analysis of Antibiotics in Drinking Water Using an Orbitrap and Online Sample Preparation

Instrument Type: LCMS

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.

Rapid Screening Method for Veterinary Antibiotics Using an Advanced Solid Core UHPLC Column and UHPLC System with MS/MS Detection

Instrument Type: LCMSMS

There is increasing demand to provide rapid and selective screening techniques for a wide range of antibiotic drugs. Their abuse as a feed supplement in food animals is of growing concern and is subject to regulations globally. Creating screening methods for multiple analytes is more cost effective than dedicated methods for fewer analytes. This application shows the advantages of using the Thermo Scientific Accucore Vanquish C18 UHPLC 1.5 µm column and Vanquish UHPLC system for the analysis of thirty-six antibiotics.

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.
