2.22.2 Injection Valve Plumbing
Figure 2-57 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
25 μL PEEK sample loop (P/N 042857) is installed between ports L (1)
and L (4).
Dionex offers sample loops in various sizes. If needed, the pre-installed
25 μL loop can be replaced with a loop that has a different sample
injection volume.
