Optionally you can vent the detector out, pump and vent ports. Use flexible tubing
fitted with luer adapters to vent these ports to a fume hood or outdoors. The detector
out ports vent the effluent from the PID (port 1) and ECD (port 2). The pressure set
by the method will determine the outlet flow rates at these ports. If the detector is
not in use
Explorer supplies a maintenance flow to ensure the detector is ready for
operation.
Samples drawn by the pump to fill and flush the sampling system are vented through
the pump out port. The flow though this port is approximately 250 ml/min when the
pump is on. The two columns that are not in use are flushed constantly with
approximately 1 mL/min. The two columns are both vented through the vent out
port.
