3.13 Injection valve
The injection valve connects the eluent and sample path. Through rapid
and precise valve switchover a precise amount of sample solution defined
by the size of the sample loop is injected and rinsed with eluent onto the
separation column.
3.13.1 Connecting the injection valve
The injection valve has six connectors: two for the sample path (connec-
tors 1 and 2), two for the eluent path (connectors 4 and 5) and two for
the sample loop (connectors 3 and 6).
Note
The capillaries of the eluent path and the sample path and the sample
loop are already installed in the newly delivered instrument.
