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™ that delivers class leading UPLC/MS/MS sensitivity. 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. You benefit from more versatility in a single instrument platform, which is adaptable to a wide variety of different UPLC/MS/MS applications both quantitative and qualitative: bioanalysis, ADME screening, food safety, environmental monitoring, forensic, and more.
