valve X2 V9-IX or V9H-IX
Second inlet valve for Sample pump to extend the
number of sample inlets up to 14.
Second Sample inlet valve
V9-S2 or V9H-S2
A 4-port, 4-position valve, which can be used to cus-
tomize the flow path.
Versatile valve V9-V or
V9H-V
Valve which enables automatic sample application from
up to five sample loops, or to collect intermediate frac-
tions in automated two-step purification.
Loop valve V9-L or V9H-L

Valve which adds 12 outlet ports to the system, giving
a total of 32 outlets
Third Outlet valve V9-O3
or V9H-O3
Sensor which prevents air from being introduced into
the flow path.
External air sensor L9-1.5
or L9-1.2
Module which receives analog or digital signals from,
or transfers analog or digital signals to, external equip-
ment that has been incorporated in the system.
I/O-box E9
Monitor which measures the UV absorbance at a fixed
wavelength of 280 nm.
Second UV monitor U9-L
Monitor which measures the conductivity of buffers and
sample solutions.
Second Conductivity
monitor C9
Round fraction collector that can collect up to 175
fractions.
