Detection of Pesticides in Drinking Water with Xevo TQ-S

Xevo™ TQ-S from Waters^® is designed for the most demanding quantitative UPLC^®/MS/MS applications. It features a revolutionary new off-axis ion source technology, known as StepWave™, which increases even further the high sensitivity provided by Xevo TQ. This advance in performance allows you to accurately, robustly, and reproducibly measure compounds at much lower concentrations than you ever thought possible. Xevo TQ-S also features ScanWave™ collision cell technology to provide enhanced spectral LC/MS/MS data acquisition capabilities. Unlike conventional tandem quadrupole mass spectrometers, the Xevo TQ-S is designed to provide not only the very best quantitative data, but also superior spectral MS/MS information. Using direct injection on Xevo TQ-S removes sample preparation and enables a simple, high-throughput analysis of pesticides in drinking water. This is possible with ultra-sensitive detection down to ppq or pg/L concentrations to enable real background concentrations in samples to be observed. The RADAR mode of acquisition enables the collection of spectral information on background components in the sample matrix while simultaneously collecting MRM data. This can help identify areas of potential ion suppression, observe untargeted contaminants, and aid in the development of matrix reduction strategies.
