When you need maximum sensitivity, the 6550 iFunnel Q-TOF LC/MS system offers unprecedented detection levels in a high-resolution system. Ideally suited for proteomics research, where MS/MS is used consistently, the system delivers high precursor abundances, allowing you to acquire fragment data faster and reduce the duty cycle substantially.
The high sensitivity of the 6550 iFunnel Q-TOF LC/MS allows for highly repetitive quantitative analyses, allowing you to see compounds at trace level. The innovative combination of hexabore capillary and ion funnel-based entrance optics allows maximum capture of your analytes, making this the most sensitive Q-TOF LC/MS for your proteomics research.
Features
- Achieve femtogram-level sensitivity with Agilent iFunnel technology, which increases ion transfer for the lowest detection levels of any high-resolution LC/MS instrument
- Benefit from a high abundance of precursors that allow a fast duty cycle of fragmentation spectra, for more effective proteomics research
- Avoid interferences and make high-resolution quantitation a reality with a powerful combination of accuracy and sensitivity
- Gain confidence in your analysis with sub-ppm mass accuracy and resolution of 45k
- See everything when screening or profiling with a wide in-spectrum dynamic range, complementing the system’s excellent detection limits and superb reproducibility
- Agilent Infinity II UHPLC, 2D-LC, SFC, and GC-APCI chromatographic interfaces deliver exceptionally fast acquisition speeds
- Features powerful MassHunter software for profiling, characterizing, identifying, and quantifying compounds in complex mixtures via high-definition MS and MS/MS
- Use of the Agilent All Ions MS/MS technique facilitates untargeted screening and quantitation
