9. CONTINUOUS MONITORING
The Quintox is designed primarily as a portable emissions monitoring analyser. It can
however be used for longer periods if the gas is treated correctly before being
supplied to the analyser.
The main problem with continuous monitoring is the build-up of water in the water
trap. There are two methods available for extracting the water. Both are optional
extras available :-
• Pump drained water trap with built-in level sensor. This connects via RS232
connections and will automatically drain the water trap if the level rises too high. The
electronics in the water trap will also stop the Quintox from pumping if the water
level does not drop.
Gas Conditioning Unit with heated line and cooled chamber. This should be used
when accurate NO2 and SO2 readings are required. A Main Purge solenoid should
also be fitted to the Quintox when monitoring for longer periods of time. This is to
supply fresh air to the sensors and hence prevent them drying out. See Recommended
Operation in next section.
