Flue Gas Sample Conditioner

Moisture Removal for Comprehensive and Accurate Measurements

Since NO2 and SO2 are absorbed by water, effective moisture removal from the flue-gas sample is of primary importance when obtaining accurate and comprehensive data, especially for emissions testing.

Used in conjunction with the ECA 450, the Flue-Gas Sample Conditioning System functions to remove water vapor from the flue-gas sample, thus preventing the formation of water droplets inside the probe hose. If water droplets were to form, a portion of the gas sample could be absorbed by the water, thus resulting in lower-than-actual NO2 and SO2 readings.

Water vapor is removed by passing the gas sample through a Peltier Cooler where the sample is chilled, causing the water vapor to condense. The water is then pumped out of the cooler and into a water trap.
