Safely Route Vent Tubing; Prepare The Cryogenic Oven Cooling System - Agilent Technologies 6850 Series II User Information

Safely route vent tubing

The FPD provides a plastic vent tube that exits the back of the detector cover.
During normal operation, this detector produces water vapor. Vent the tubing
appropriately.
The µECD provides a vent tube that exits the back of the lid. Connect this tube
to a fume hood or other location as directed by your radiation safety officer or
environmental health and safety organization. See

concentrations is toxic to humans; take precautions to prevent hazardous
concentrations. Consult your local supplier for recommended safety
precautions and delivery system design.
Warning
Do not use copper tubing or thin-wall stainless steel tubing with liquid CO
Both harden at stress points and may explode.
Caution Liquid CO
because the expanding liquid may form solid CO
