Each valve order includes a 110 to 240 VAC to 24 VDC universal power supply. Each order includes a microelectric actuator allowing both manual and computer automated control (RS-232). Injecton
Valve Tutorial: With the valve in Position A, sample flows through
the external loop while the carrier flows directly through to the detector.
When the valve is switched to Position B, the sample contained in the sample
loop and valve flow passage is injected onto the detector.
Selector (multiposition) Valve Tutorial: The selected valve port is made "common" with the center port. The center port is usually connected to a syringe or peristaltic pump. See tutorial on FIA/SIA for additional discussions.
