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.
The separation of 52 Polycyclic Aromatic Hydrocarbons including the low volatility dibenzopyrenes was performed on a specifically designed Thermo Scientific TraceGOLD TG-PAH GC column
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).
Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants produced by both human activities and natural phenomena. PAHs enter surface waters mainly by atmospheric fallout, urban runoff, municipal and industrial effluents, and the spill or leakage of petroleum and its derivates. We developed a fast, fully automated protocol for determining a large number of parent PAHs and alkylated PAHs in environmental waters, using online solid–phase extraction coupled with liquid chromatography and tandem mass spectrometry.
In this study, a fast, easy, and robust workflow was used to analyze pesticide residues in baby food. Accurate and sensitive detection, quantification, and identification of pesticides in baby foods is of particular importance because babies are more vulnerable to adverse health effects from these chemicals.
