Introduction to the Autosampler
1
Sampling Unit
Injection-Valve
The two-position 6-port injection valve is driven by a stepper motor. Only five
of the six ports are used (port 3 is not used). A lever/slider mechanism
transfers the movement of the stepper motor to the injection valve. Two
microswitches monitor switching of the valve (bypass and mainpass end
positions).
No valve adjustments are required after replacing internal components.
