Specialized quantitative applications, including ADME screening, bioanalysis, clinical analysis, as well as food safety and environmental monitoring, require high sensitivity, high performance LC/MS/MS instrumentation. Compliance with stringent regulatory guidelines may also be necessary with these applications.Compact size - Uses only 18.9" (48 cm) of linear benchspace.T-Wave collision cell for optimum performance at fast acquisition rates and a polarityswitching time of only 20 ms ensures that the Quattro Premier XE is ideally suited to the demands of UPLC.Dynamic range—up to 5 orders of magnitude for accurate determination across a wide concentration range.Data Directed Analysis for intelligent, automated MS to MS/MS switching within a single analytical run.The new low-noise WhisperTM detector in the Quattro Premier XE provides a detectionefficiency approaching 100% for single ions. Situated after the second analyzer andfeaturing integral focusing optics, the detector‘s high voltage dynode and phosphor arepositioned 90 ̊ off-axis to eliminate neutral noise. The detector can rapidly switch polarity(20 ms), allowing the detection of both positive and negative ions in a chromatographicpeak. In addition, the detector’s robust photomultiplier tube is sealed for life in a vacuumenvelope, guaranteeing years of maintenance free service.
