vetdrugs explorer collection

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.

trace analysis pharmaceuticals organic contaminants water

Trace analysis of pharmaceuticals and organic contaminants in water

Instrument Type: LCMSMS

We present the reliable and accurate quantitative analysis of contaminants at the pg/mL level in drinking water using the Thermo Scientific EQuan MAX Plus LC-MS system coupled to the Thermo Scientific TSQ Endura triple quadrupole mass spectrometer. Excellent reproducibility was shown for the target compounds in tap water using 1 mL injections at 0.37× maximum effluent concentration.

forensic screening for drugs urine using highresolution msms spectra simplified highperformance screening software

Forensic Screening for Drugs in Urine Using High-Resolution MS/MS Spectra and Simplified High-Performance Screening Software

Instrument Type: LCMSMS

Forensic toxicologists need an economical solution to screen for a virtually unlimited number of compounds in urine. Here we present a method for screening using a dilute-and-shoot approach with the Q Exactive Focus mass spectrometer and Thermo Scientific ToxFinder software. For forensic use only.

high resolution lcms for screening quantitative analysis antibiotics drinking water using an orbitrap online sample preparation

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 uhplc system with msms detection

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.
