The aim of this application note is to demonstrate the performance of the Thermo Scientific™ TSQ™ 9610 triple quadrupole mass spectrometer coupled to the Thermo Scientific™ TRACE™ 1610 GC equipped with programmable temperature vaporizing injector (PTV) for the determination of trace level pesticide residues in baby food.
In this study, the quantitative performance of the Thermo Scientific™ TSQ™ 9000 triple quadrupole GC-MS/MS system was assessed for the analysis of more than 200 pesticides in baby food at ultra low concentrations (as low as 0.025 μg/kg).
The Thermo Scientific™ TSQ™ 8000 Evo triple quadrupole GC-MS is an excellent tool for the control of MRL levels in food commodities. The enhanced velocity optics (EVO) driving EvoCell collision cell technology provide high SRM transition speeds, precision, and sensitivity for even complex methods involving several pesticides in a short run time. This application is focused on the analysis of 247 compounds in two different herbal juices, Aloe vera and Amla (Indian gooseberry), demonstrating the potential of the method to detect trace level compounds at concentrations as low as 1-2 ng/g.
As agricultural trade grows and food safety concerns mount, stricter pesticide regulations are being enforced around the world. Increased pesticide testing and reductions in maximum permissible residue levels have driven demand for fast, sensitive and cost-effective analytical methods for high-throughput screening of multi-class pesticides in food. Detection of 510 pesticides at low ppb levels was achieved within 12 minutes using the Thermo Scientific Exactive benchtop LC/MS system powered by Orbitrap technology.
Comprehensive assessment of the aquatic fate and effects of organic micropollutants is greatly hindered by the need to develop compound-specific methodologies prior to sampling and analysis. We descrbe a data-driven workflow, coupling high-resolution, accurate-mass (HRAM) mass spectrometry and highly sensitive online solid phase extraction (SPE) analysis that ensures complete characterization of organic pollutants in aquatic environments.
