Brochures
Thermo Scientific Pesticide Explorer Collection
This brochure lists technical information for the Thermo Fisher Scientific Pesticide Explorer Collection. The Thermo Scientific™ Pesticides Explorer Collection is a comprehensive set of liquid chromatography-mass spectrometry (LC-MS) solutions designed for laboratories performing routine quantitation, targeted and non-targeted screening of pesticide residues in food matrices.
QuEChERS solutions in all your favorite flavors
In this application note, Thermo Fisher Scientific presents QuEChERS solutions. Fast, easy, and cost-effective, QuEChERS is a robust, reproducible approach for extracting and cleaning up pesticides and other low-level contaminants in complex matrices. It is often used as a sample preparation step prior to GC-MS or LC-MS analysis, and can be automated for higher throughput.
Multi-pesticide residues analyses of QuEChERS extracts using an automated online μSPE clean-up coupled to LC-MS/MS
In this application note, Thermo Fisher Scientific presents a fully automated and online μSPE clean-up procedure with LC-MS/MS, which aims to be a reliable, accurate, reproducible, and robust solution for the multi-residue pesticide analysis in representative samples of different matrix complexity (grape, rice, and tea).
Unmasking the rising threat of mycotoxins in the global food and feed supply chain
In this infographic, we explore how a rise in global temperatures due to climate change could mean countries in cool or temperate climates are more at risk for mycotoxin contamination in food and animal feed supply chains. Discover insights into legislation, global prevalence, socioeconomic impacts, and how manufacturers are innovating to help institutions optimize their testing capabilities to comply with international trade regulations and ultimately, ensure food safety.
Tackling the residual problem of pesticides: A challenge in the global food supply chain
Residual pesticide testing is an important factor in ensuring global food safety and improved nutrition. In this informative infographic, we explore the international impact of the pesticide problem, socioeconomic risks involved in pesticide use, what can be done, and how scientists can streamline their path to multi-residue testing.
Analysis of Low Level Pyrethroid Pesticides in Water
In this study, a simple method for isolating pyrethroids from water at low ng/mL levels was performed using solid-phase extraction (SPE) followed by GC/MS utilizing a programmable temperature vaporizer (PTV) operated in simulated on-column injection mode. The separation of the pyrethroid (bifentrin, permethrin, cyfluthrin, cypermethrin and flumethrin) extracts was carried out using a Thermo Scientific™ TraceGOLD™ TG-5SilMS column and GuardGOLD™ pre-column.
Fast Screening and Quantification of Pesticide Residues using a Comprehensive LC-MS Solution: The Pesticide Explorer Collection – Standard Quantitation
Pesticides are chemicals used on crops to protect them from the negative activity of pests. Inappropriate application of pesticides can have adverse effects on health; therefore, determination and quantification of pesticide residues in foods and food products is an important part of routine food control. The aim of this application note is to present a fully tested LC-MS/MS workflow for rapid and robust quantification of more than 250 pesticides below maximum residue limits (MRLs) with sensitivity, accuracy, and precision that meets stringent EU guidelines.
