Abstract: Moisture is removed from stack gas prior to measuring concentrations of gaseous constituents in the stack gas. A sample of the stack gas is passed through a cooling zone wherein the gas is cooled to a temperature in the range of about 40.degree.-45.degree. F., after which the cooled gas is passed through a condenser. The gas rises through the condenser wherein water condenses out of the gas and falls by gravity into a U-shaped trap. A drain passage communicates with the downstream side of the trap whereby condensed water can be drained periodically out of the trap to control the amount of water in the trap. The dried gas passes out of the condenser into one or more gas constituent monitoring stations.
