Quantitating pesticides in black tea with steady performance and maximized uptime by GC/MS/MS
29 Jul 2024Tea is one of the most commonly consumed non-alcoholic beverages globally, and assessing pesticide levels in tea is essential for ensuring safe consumption, as required by many multinational regulatory bodies. Agilent Technologies presents a complete GC/TQ workflow solution for the accurate and reliable analysis of 246 volatile and semivolatile pesticides in black tea, with the Agilent 7010D GC/TQ. Discover how this workflow solution allows for quantitation of pesticide residues with LOQs as low as 0.01 ppb, yet also demonstrates calibration accuracy over a dynamic range, spanning up to five orders of magnitude over 0.01 to 1,000 ppb in the complex black tea extract.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
