UHPLC-QTOF-MS



  • Achieve femtogram-level sensitivity – iFunnel increases ion transfer to achieve the lowest detection levels of any high resolution LC/MS instrument.
  • Maintain resolution and mass accuracy – Ion Beam Compression and Shaping (IBCS) technology provides the greatest sensitivity while maintaining 40k mass resolution and sub ppm mass accuracy from m/z 20-10,000.
  • Reach new scan speeds – New electronics and software algorithms enable scanning of up to 50 spectra per second.
  • Improve sensitivity for high-throughput applications – Agilent Jet Stream technology combined with improved ion optics provide 5x greater on-column sensitivity and increase up time to maintain the highest sensitivity for high throughput applications.
  • Increase dynamic range – In-spectrum dynamic range of up to 5 orders of magnitude reveals trace-level targets, even in the presence of much more abundant compounds.
  • Ensure high-quality data – Automated tuning optimizes system performance to ensure high quality data for a broad spectrum of applications.
  • Powerful MassHunter Workstation Software takes advantage of accurate mass MS and MS/MS and high definition isotopic data to facilitate profiling, characterization, identification and quantification of compounds in complex mixtures.
  • New All Ions MS/MS Technique for Targeted and Untargeted Screening on TOF and Q-TOF LC/MS
