In the Inject position, carrier liquid flows through the sample loop and
on to the concentrator column, carrying the contents of the sample
loop with it. Excess flows out to waste. Eluent flows from the pump,
through the valve, and to the separator column, bypassing the
concentrator column.

Figure 2-18 shows the injection valve connections for the 6-port valve.
The injection valve is plumbed at the factory with all tubing and fittings
for connection to the pump, sample loading port, column, and waste. A
10
μ
L PEEK
™
sample loop (P/N 042949) is installed between ports L (1)
and L (4).
Dionex offers sample loops in various sizes. If needed, the pre-installed
10
μ
L loop can be replaced with a loop that has a different sample
injection volume.
