The Dual Ion Funnel (DIF) technology is the next enhancement.
The DIF technology removes the gas and neutral noise but
captures the ions. It also extends the turbo pump’s lifetime. The
Dual Ion Funnel technology can transmit ions efficiently at as
high a pressure as possible. The first ion funnel has a pressure
between 7 and 14 torr. The second ion funnel is a low pressure
ion funnel (1 to 3 torr). The ion funnel works by having the RF
voltage focus the ions to the center and having the DC voltage
accelerate the ions to the exit. See Figure 14.

Ion Beam Compression Technology
The first improvement is the Ion Beam Compression Technology
(IBC) which cools and focuses the ion beam. This technology
simultaneously maximizes ion transmission and reduces beam
divergence. Active Ion Beam Compression is achieved with
Agilent’s Axial Ion Acceleration Technology applied to a
tapered ion guide design.
Ion beam compression provides up to a 10-fold compression and
cooling which helps in creating a much denser and thinner ion
beam that passes through a narrower slit leading into the slicer
