Abstract
A water trap for a gas analyzer includes self-sealing filters formed of a porous polymer that includes a cellulose extract that causes the polymer to become impermeable on contact with water. The water trap in this way automatically protects the gas analyzer from liquid contamination. Preferably, the gas analyzer monitors a pressure parameter of a pneumatic line connected to the water trap and provides an indication that the water trap should be replaced in the event this pressure parameter indicates an abnormal operating condition.
