1Overview
Innovative Enhancements in the Agilent 6550 iFunnel Q-TOF
Ions are generated using an electrospray ion source where the
analyte is simultaneously ionized and desolvated from the
liquid matrix. The iFunnel includes the application of Agilent
Jet Stream Technology (first introduced with the 6530) which
improves sensitivity via thermal gradient focusing and
enhanced desolvation.
The next innovative enhancement is the use of a short hexabore
capillary. It has 6 capillary inlets and samples up to 10X more
ion rich gas from the source. It captures the majority of the gas
from the source region. See Figure 13. The hexabore capillary
transmits a high gas/ion volume into the ion optic system.
