How each component works to improve sensitivity
This section describes in more detail how each of the 
components of the Agilent 6400 Series Triple Quadrupole MS 
contributes to reducing noise (Figure 17).
Agilent iFunnel Technology
Agilent’s iFunnel Technology which is available on the Agilent 
6490 Triple Quadrupole consists of the Agilent Jet Stream 
technology, the Hexabore Capillary and the Dual Ion Funnel. 
The Agilent Jet Stream technology is discussed below. The 
Hexabore Capillary samples up to 10 times more ion rich gas 
from the source. It captures the majority of the gas from the 
source region. The Dual Ion Funnel (DIF) technology removes 
the gas but captures the ions. It also removes the neutral noise.
