2.23 Injection Valves
The TC is available in the following configurations:
2.23.1 Injection Valve Operation
The 6-port injection valve has two operating positions: Load and Inject.
Liquid flows through either the Load or Inject path, depending on the valve
position.
Figure 2-64 shows flow schematics for the 6-port valve.
•
In the Load position, sample is loaded into the sample loop, where it is
held until injection. Eluent flows from the pump, through the valve, and
to the column, bypassing the sample loop. Sample flows from the syringe
